Lighthouse is a permanent file storage protocol that allows the ability of perpetual storage for your files. Using Lighthouse you can store your files forever on a distributed web. Lighthouse aims to be the best entrypoint to your files on filecoin network, abstracting away all complexities and with added functionality of permanent and long term storage.

## Private Data


![encryption2.jpg](/uploads/encryption2_7fbabc718a.jpg)


Till now, most of the data stored on Filecoin and IPFS network is public that can be accessed by anyone. Hence, you can’t store files directly on a public network that are sensitive like personal photos, patient data, enterprise data, etc. This leads to developers and users hanging on to build their own encryption layer to store data on storage networks and can often lead to bad practices and over burden of access and key management. This also further leads to centralised key management for files or bad user experience to manage your own keys for files. Not to say, the trouble caused by sharing the files to authorised parties is even more problematic.


That’s why we at Lighthouse choose to build an encryption layer and access control for users to store private and sensitive data on filecoin. Using this functionality, developers need not worry about creating their own encryption layer for users and managing keys via unhealthy practices. 
 

##  How it works


Lighthouse Encryption and Access Control uses BLS threshold cryptography to ensure that any file’s decrypt key and data stays consistent and is resistant to faults and attacks. Threshold cryptography ensures that even when some parties or nodes in a system are compromised the system architecture is robust enough to keep serving users and also ensuring the data secrecy.



Furthermore, Lighthouse at no point in time receives or collects decrypt keys of any file or documents. All decrypt keys are randomly generated and fragmented from the user’s end. After which, the shards are encrypted and stored on nodes alongside user defined access conditions. 


Retrieving keys has never been easier, our architecture only required the user to sign a randomly generated message, specify the CID of the file or document to be retrieved. After which each node validates the request and access condition independently and sends a copy of the key shards they have in their possession if the access condition(s) are valid which is then aggregated on the user’s end to decrypt the file or document


##  Use Cases


This new functionality will enable variety of use cases for applications to store their private and encrypted data on Lighthouse, some of which are listed below - 


- Encrypted backup of files on Filecoin


- Storing personal photos on dweb


- Token gated applications


- DAOs can store data generated by members


- DataDAOs building collectives of data


- Restrict access to files by owners of a NFT collection


- Sensitive data like patient data can be stored


- Enterprises can store their data on a distributed web for lower cost


- Recordings for web3 meetings


- Private code repositories storage

[Lighthouse](https://www.lighthouse.storage/) is a decentralized storage protocol that utilizes the power of Filecoin and IPFS to provide perpetual storage for your files. Unlike traditional storage solutions, Lighthouse offers a number of advantages, including encryption and access control, as well as cost savings over alternatives.

![image2.png](/uploads/image2_bc79ea5e46.png)


Migrating files to Lighthouse is a relatively straightforward process, allowing you to migrate your files from any IPFS node which is on a public network, and it can be done using the CID (Content Identifier) of the files you wish to move. In this article, we will walk you through the steps of migrating both a single CID and multiple CIDs to Lighthouse.

## Steps for Migrating Using CID:
- Copy the CID of the file you want to migrate from your current storage provider.

- Go to https://files.lighthouse.storage/ and log in to the Lighthouse Files Dapp.

- Go to the Migration tab on the left side of the page.

- Click on the "Create Migration" button and paste the CID into the field provided. Press the spacebar, and then press the "Migrate CID" button.

- Wait for the CID to migrate. You can check the status of the migration in the "Status" column.

**NOTE: You can also Upload a CSV File containing a list of all the CID separated by a comma**


It's important to note that migrating your files to Lighthouse can take some time, depending on peer discoverability in the IPFS network, the size of your data, and the speed of your internet connection. However, once the migration is complete, you just created another replication of your file on the IPFS Network, also a Filecoin deal will get created for the migrated file by Lighthouse.
In conclusion, migrating your data to Lighthouse is a great way to ensure that your files are stored securely. Lighthouse is also cheaper than alternatives and provides perpetual storage. With its easy-to-use platform and simple process, you can migrate your files to Lighthouse with ease.

## Introduction
Lighthouse is now bringing decentralized storage to the entire Ocean Protocol Ecosystem. Using Lighthouse — Ocean data publishers, marketplaces, and dapps will now have access to storing data on the Filecoin network leading to net positive value generation due to the low storage cost across thousands of active miners in the filecoin economy.

## Ocean Protocol for the new data economy

![1_7HiWEKsVLrh1ezHR8Wer5w.webp](/uploads/1_7_Hi_WE_Ks_V_Lrh1ez_HR_8_Wer5w_d5feae6b05.webp)

Data is the essential resource of modern times and is the new oil. However, unlike oil, which burns and exhausts, data sharing and usage lead to more innovation and a better digital society.

Blockchain technology has enabled a new data economy which is Ocean Protocol. Ocean Protocol bridges the gap between data supply and demand, allowing data availability for the researchers and providing a fair share of revenue to the data owners. Especially in the current market scenario, we have seen companies exert tight control over data and not let anybody outside access it.

Hence, this led to closed-source ChatGPT models at OpenAI and the recent acquisition of GitHub by Microsoft, leading to AI models being controlled and developed by just a few, due to restricted access to data.

## Lighthouse — perpetual storage on Filecoin

![1_X-d6MBzNHB0kOMsDdeptpQ.webp](/uploads/1_X_d6_M_Bz_NHB_0k_O_Ms_Ddeptp_Q_db9353d9e4.webp)

Lighthouse is a perpetual storage protocol built on Filecoin that allows storing your data long-term with a one-time fee. In addition, Lighthouse Storage provides encryption and access control functionality to store private data and create token-gated access to resources. Along with fast gateways to stream 4k videos through its IPFS Gateways, Lighthouse Storage is the feature-rich way to use IPFS and Filecoin.

## Decentralized Backend Storage
Ocean Protocol provides the ability to share data through its app-level interface, like ocean marketplaces and middleware, to compute over data using a privacy-preserving method, i.e., using data without it leaving the premise of the data owners. Data owners can also keep data with a trustful entity like Ocean Protocol Foundation — a non-profit organization.

Given the presence of web3 storage systems like Filecoin, there is a demand from the Ocean Protocol ecosystem to store data there. Hence, with the support of the Ocean Protocol team, Lighthouse Storage is chosen for the integration from the Ocean Economy to Filecoin via the Decentralized Backend Storage (DBS) created by the Ocean Protocol team.

This backend (DBS) provides the following functionality

- allow users to upload content

- handle payments

- push the content to decentralized storage using Lighthouse Storage

- return the storage object to be used in the DDO

- Hence, the aim is to improve UX for the data publishers on the Ocean Protocol and provide them with ways to store their data on a decentralized network.


![1_VrGLhETjXZ_UsAHLKm1ZCQ.webp](/uploads/1_Vr_G_Lh_E_Tj_XZ_Us_AHL_Km1_ZCQ_2a03aef88d.webp)


Filecoin microservice by Lighthouse Storage registers itself to DBS, using the Register endpoint every 10 minutes per the DBS Spec. The microservice exposes the following API Endpoints:

- GetQuote — Gets a quote to store some files

- Upload — Upload some files

- GetStatus — Gets status for a job

- GetLink — Gets DDO files object for a job

## Summary
Lighthouse Storage is now integrated into the Ocean Protocol, which has led to an important piece being attached to the data economy puzzle. The Lighthouse team will continue supporting the Ocean dapps, data publishers, and marketplaces to store data on web3.

As the world is advancing towards a more decentralized web infrastructure, storage solutions such as [Lighthouse Storage](https://www.lighthouse.storage/) are becoming increasingly popular. Lighthouse Storage is a Web3 Storage Solution that allows users to store their files perpetually on Web3 using Filecoin. Lighthouse Storage can be utilized for creating a pay-to-view model, using custom contracts and NFT-based access control.

![Twitter post - 16 (1).png](/uploads/Twitter_post_16_1_df9e3f8bf5.png)

The concept of pay-to-view is not new, but with the rise of blockchain technology, it has become more feasible and secure. With Lighthouse Storage, users can upload their files with encryption, and apply access conditions to them. These access conditions can be defined using NFTs, custom contracts, time-based, or native token-based conditions. In this example, we will consider NFT-based access control.

**Step 1:**
Upload the encrypted file to the Lighthouse IPFS node. Users can choose to upload their files either using [NodeJS Encryption](https://docs.lighthouse.storage/lighthouse-1/lighthouse-sdk/code-examples/nodejs-backend/nodejs-encrypt) Upload or [ReactJS Browser Encryption](https://docs.lighthouse.storage/lighthouse-1/lighthouse-sdk/code-examples/browser-frontend/browser-with-encryption) Upload code example. Once the file is uploaded, Lighthouse node returns an IPFS CID/Hash for the encrypted file.

**Step 2:**
Apply access control to the encrypted file. Let's consider the example of NFT-based access control. The file owner can specify that only users who own NFTs from a particular collection can access the file. To do this, the owner needs to apply the access condition to the encrypted file. After applying the access condition, only the user who owns NFTs from that particular collection can access the file.

**Step 3:**
Once the access conditions have been defined, the Lighthouse view URL can be used to view the encrypted file, or the user can build a custom decryption view page using the provided [code example](https://docs.lighthouse.storage/lighthouse-1/lighthouse-sdk/code-examples/browser-frontend/decrypt-file). The user who has access to the file can pay using NFT or custom contracts. If the NFT is made a soul-bound token (SBT), the owner will not be able to transfer it to any other address, ensuring that the access is limited to the intended user.

## Introduction

Welcome to the beginner's tutorial on using the Lighthouse Python SDK for perpetual and decentralized file storage. Lighthouse is a cutting-edge file storage protocol that revolutionizes the traditional rent-based cost model of cloud storage by enabling users to pay once for their files and store them forever. With the integration of IPFS, Filecoin, and smart contracts on various blockchain networks, Lighthouse ensures data permanence, enhanced security, and cost-efficiency. This tutorial will guide you through the essential steps of leveraging the Lighthouse Python SDK to manage files perpetually on the decentralized network.

## Why Lighthouse Python SDK?

Traditional file storage models require users to periodically renew their storage subscription, leading to recurring costs and management efforts. Lighthouse Python SDK eliminates these hassles by offering a perpetual storage model, where users pay once and store files indefinitely. This innovative approach utilizes the robustness of IPFS and the storage capacity of Filecoin's miner network, guaranteeing file permanence and redundancy. Let's dive into the Lighthouse Python SDK to harness the power of perpetual decentralized file storage.

## Prerequisites

Before starting with the Lighthouse Python SDK, ensure you have the following:

1. Basic knowledge of Python programming.
2. Python installed on your computer.
3. A Lighthouse API token. If you haven't obtained one yet, sign up on the Lighthouse website to get your API token.

### **************Step 0:************** Getting your lighthouse API key [Files-Lighthouse-storage](https://files.lighthouse.storage/):

1. Go on https://files.lighthouse.storage/ and Click on Login

    ![Untitled design.png](/uploads/Untitled_design_8522f03964.png)

### **Step 1:** Install the Lighthouse Python SDK

Begin by installing the Lighthouse Python SDK via pip, allowing you to interact with the Lighthouse protocol seamlessly:

```bash
pip install lighthouseweb3
```

### **Step 2:** Import the Lighthouse Python SDK and Initialize

After installing the SDK, import the required libraries and initialize the Lighthouse client with your API token:

```python
import io
from lighthouseweb3 import Lighthouse

# Replace "YOUR_API_TOKEN" with your actual Lighthouse API token
lh = Lighthouse(token="YOUR_API_TOKEN")
```

### **Step 3:** Upload a File

Next, let's upload a file to Lighthouse. We can use the **upload** function for this purpose. We'll demonstrate both regular file upload and file upload with tags:

```python
# Regular file upload
source_file_path = "./path/to/your/file/or/directory"
upload = lh.upload(source=source_file_path)
print("Regular File Upload Successful!")

# File upload with tags
tagged_source_file_path = "./path/to/your/file/or/directory"
tag = "your_tag_name"
upload_with_tag = lh.upload(source=tagged_source_file_path, tag=tag)
print("File Upload with Tag Successful!")
```

### **Step 4:** Get Upload Information

After uploading a file, you might want to retrieve its information, such as the Content Identifier (CID). We can use the **getUploads** function for this purpose:

```python
# Replace "YOUR_CID_TO_CHECK" with the actual CID you want to check
file_cid_to_check = "YOUR_CID_TO_CHECK"
list_uploads = lh.getUploads(file_cid_to_check)
print("Upload Information:")
print(list_uploads)
```

### **Step 5:** Download a File

Now, let's download a file from Lighthouse using its CID. We'll use the **download** function to achieve this:

```python
# Replace "YOUR_CID_TO_DOWNLOAD" with the actual CID of the file you want to download
file_cid = "YOUR_CID_TO_DOWNLOAD"
destination_path = "./downloaded_file.txt"

file_info = lh.download(file_cid) # The file_info is a tuple containing the file content and its metadata

file_content = file_info[0] # Save the downloaded file to the destination path

with open(destination_path, 'wb') as destination_file:
	destination_file.write(file_content)

# The file has been successfully downloaded and saved to the destination_path
print("Download successful!")
```

### **Step 6:** Check Deal Status

Lighthouse allows you to check the status of a file's deal on the network. This can be useful to ensure that the file is accessible and replicated. Use the **getDealStatus** function to check the deal status:

```python

# Replace "YOUR_CID_TO_CHECK_STATUS" with the actual CID whose deal status you want to check
file_cid_to_check_status = "YOUR_CID_TO_CHECK_STATUS"
deal_status = lh.getDealStatus(file_cid_to_check_status)
print("Deal Status:")
print(deal_status)
```

### **Step 7:** Download Files by Tag

If you've tagged your files during the upload, you can easily retrieve them by tag using the **getTagged** function:

```python
# Replace "YOUR_TAG_TO_DOWNLOAD" with the actual tag name you want to download files for
tag_to_download = "YOUR_TAG_TO_DOWNLOAD"
downloaded_files_with_tag = lh.getTagged(tag_to_download)
print("Files Downloaded with Tag:")
print(downloaded_files_with_tag)
```

# Conclusion

Congratulations! You have successfully learned how to interact with the Lighthouse API for file upload, download, tagging, and checking deal status. You can now integrate Lighthouse into your own applications to manage files securely and efficiently. Keep exploring the Lighthouse documentation to discover more features and functionalities offered by the platform.

Remember to handle exceptions appropriately in your applications, and make sure to secure your API token to protect your data on the Lighthouse platform. Happy coding!

# **Introduction:**

Lighthouse IPNS (InterPlanetary Naming System) is a valuable tool that enables the creation of mutable pointers to content-addressed data in the IPFS (InterPlanetary File System) network. While IPFS ensures content immutability by generating unique CIDs for each piece of data, IPNS allows for regular updates to the content while retaining a consistent address. In this tutorial, we will explore two methods to publish and update content with Lighthouse IPNS: using the CLI (Command Line Interface) and Node.js. By the end of this guide, you will be able to effectively publish and manage IPNS records, making your content easily accessible and updatable.

# **Prerequisites:**

**Before we get started, ensure you have the following:**

1. Basic understanding of [IPFS](https://docs.ipfs.tech/) and [IPNS](https://docs.ipfs.tech/concepts/ipns/) concepts.
2. [Node.js](https://nodejs.org/en/download) installed on your system (for Node.js method).
3. [Lighthouse CLI](https://docs.lighthouse.storage/lighthouse-1/cli-tool/overview) installed (for CLI method).

## **Understanding Mutability in IPFS:**

In IPFS, content is typically addressed using CIDs, making it immutable. However, there are scenarios where content needs to be regularly updated, such as publishing a frequently changing website. IPNS addresses this challenge by creating mutable pointers to CIDs, known as IPNS names. These names act as links that can be updated over time while maintaining the verifiability of content addressing. Essentially, IPNS enables the sharing of a single address that can be updated to point to the new CID whenever content changes.

**How IPNS Works:**

1. **Anatomy of an IPNS Name:** An IPNS name is essentially the hash of a public key. It is associated with an IPNS record that contains various information, including the content path (/ipfs/CID) it links to, expiration details, version number, and a cryptographic signature signed by the corresponding private key. The owner of the private key can sign and publish new records at any time.
2. **IPNS Names and Content Paths:** IPNS records can point to either immutable or mutable paths. When using IPNS, the CID's meaning in the path depends on the namespace used:
    - **/ipfs/cid**: Refers to immutable content on IPFS, with the CID containing a multihash.
    - **/ipns/cid-of-libp2p-key**: Represents a mutable, cryptographic IPNS name that corresponds to a libp2p public key.

## Step 0: Getting your lighthouse API key [Files-Lighthouse-storage](https://files.lighthouse.storage/):

1. Go on https://files.lighthouse.storage/ and Click on Login

# Store and Update content on IPNS using Lighthouse:

## **Method 1: Using Lighthouse CLI**

- **Step 1:** Generate an IPNS key using the Lighthouse CLI:
    
    ```bash
    lighthouse-web3 ipns --generate-key
    ```
    
    This command will return an IPNS name and ID, which we will use later to publish the content.
    
   ![Untitled (4).png](/uploads/Untitled_4_21b432afa4.png)
    

- **Step 2:** Make a test file, text.txt:
    
    ```bash
    echo "Hello World" >> text.txt
    ```
    

- **Step 3:** Publish this file to the IPFS using [lighthouse upload](https://docs.lighthouse.storage/lighthouse-1/cli-tool/cli-commands/upload):
    
    ```bash
    lighthouse-web3 upload ./text.txt
    ```
    
    ![Untitled (5).png](/uploads/Untitled_5_52cd5e9668.png)
    

- **Step 4:** Publish the content using the generated IPNS key and the CID of the data you want to publish:
    
    ```bash
    lighthouse-web3 ipns --publish --key=8f4f116282a24cec99bcad73a317a3f4 --cid=QmWATWQ7fVPP2EFGu71UkfnqhYXDYH566qy47CnJDgvs8u
    ```
    
    You will receive a link that can be used to access the published content. This link will remain valid even if the content's IPFS hash changes.
    
    ![Untitled (6).png](/uploads/Untitled_6_b4a120c4b2.png)
    

### ****************Updating CID:****************

- Upload another file text2.txt:
    
    ```bash
    echo "Hello World2" >> text2.txt
    ```
    
- Publish this file to the IPFS using [lighthouse upload](https://docs.lighthouse.storage/lighthouse-1/cli-tool/cli-commands/upload):
    
    ```bash
    lighthouse-web3 upload ./text2.txt
    ```
    
    ![Untitled (7).png](/uploads/Untitled_7_b447b33b51.png)
    

- Update the content using the generated IPNS key and the CID of the data you want to publish:
    
    ```bash
    lighthouse-web3 ipns --publish --key=8f4f116282a24cec99bcad73a317a3f4 --cid=QmanCeGkwsaCUHaNT24ndriYTYSwZuAy4JDifdYZpHdmRa
    ```
    
    You will receive a link that can be used to access the published content. This link will remain valid even if the content's IPFS hash changes.
    

**List all IPNS** records associated with your Lighthouse account:

```bash
lighthouse-web3 ipns --list
```

This will display a list of IPNS records with their corresponding keys and CIDs.

![Untitled (8).png](/uploads/Untitled_8_ca5b79eb3f.png)

**Remove** an IPNS record:

```bash
lighthouse-web3 ipns --remove 8f4f116282a24cec99bcad73a317a3f4
```

This step allows you to remove an IPNS record if needed.

![Untitled (9).png](/uploads/Untitled_9_3d6314b401.png)

## **Method 2: Using Node.js**

**Step 0:** Get API keys from Lighthouse as explained above.

**Step 1:** Import the Lighthouse package and set up your API key:

```jsx
import lighthouse from '@lighthouse-web3/sdk';
const apiKey = process.env.API_KEY; // Replace this with your actual API key
```

**Step 2:** Generate an IPNS key using the Lighthouse SDK:

```jsx
const keyResponse = await lighthouse.generateKey(apiKey);
console.log(keyResponse.data);
```

This will return an IPNS name and ID, which we will use in the next steps.

**Step 3:** Publish the content using the generated IPNS key and the CID:

```jsx
const pubResponse = await lighthouse.publishRecord(
  "QmWC9AkGa6vSbR4yizoJrFMfmZh4XjZXxvRDknk2LdJffc",
  keyResponse.data.ipnsName,
  apiKey
);
console.log(pubResponse.data);
```

You will receive a response containing the IPNS name and the link to access the published content.

**Step 4:** Get all IPNS keys associated with your Lighthouse account:

```jsx
const allKeys = await lighthouse.getAllKeys(apiKey);
console.log(allKeys.data);
```

This step allows you to retrieve a list of all IPNS keys associated with your account.

**Step 5:** (Optional) Remove an IPNS key:

```jsx
const removeRes = await lighthouse.removeKey(keyResponse.data.ipnsName, apiKey);
console.log(removeRes.data);
```

This step enables you to remove an IPNS key if necessary.

# **Conclusion:**
Lighthouse IPNS is a powerful mechanism for publishing and updating content on the IPFS network. By combining the benefits of content-addressing with the flexibility of mutable pointers, IPNS ensures your content remains accessible and updatable. In this guide, we covered two methods to utilize Lighthouse IPNS: the CLI and Node.js. Armed with this knowledge, you can confidently publish and manage IPNS records, creating a more dynamic and user-friendly experience on the decentralized web.

## Introduction
In this tutorial, we delve into the innovative concept of Time-Lock Encryption on the InterPlanetary File System (IPFS) using Lighthouse Access Control. IPFS, often referred to as the distributed web, offers a decentralized protocol to make the web faster, p2p, and more open. On the other hand, Lighthouse.Storage is a Web3 decentralized storage solution, offering perpetual storage to store your data securely long-term.

The amalgamation of these two technologies brings forth an exciting feature – the ability to encrypt files and set conditions for their decryption based on specific blockchain parameters. One of the innovative concept it enables is "Time-Lock Encryption."

What exactly does this mean? Think of it as a time capsule. You can securely store a piece of information, and set a condition that this information will only be accessible after a particular block number on the blockchain like ethereum has been reached. Such a feature has a myriad of applications, from securing early-stage project details to establishing wills or contracts that are meant to be executed in the future.

## This tutorial will walk you through the following:

1. Preparing your environment for Lighthouse.Storage.
2. Encrypting and uploading a file onto IPFS.
3. Setting a blockchain-based time-lock condition for accessing this file on optimism chain.
4. (Optional) Retrieving the conditions set on a file.

Whether you're a blockchain enthusiast, a developer looking to integrate time-lock features, or someone curious about decentralized storage and its potential, this guide is tailored for you.

Let's embark on this journey and unlock the potential of Time-Lock Encryption on IPFS using Lighthouse Storage.

    - Initialize a new Node.js project:
        
        ```bash
        npm init -y
        ```
        
    - Install required local dependencies:
        
        ```bash
        npm install dotenv ethers
        ```
        
    1. **Security Configuration**:
    - Within your project directory, create a **.env** file.
    - Inside **.env**, add your Lighthouse API key and private key:
        
        ```makefile
        API_KEY=Your_Lighthouse_API_Key
        PRIVATE_KEY=Your_Private_Key
        ```
        
    - Always ensure your **.env** file is added to **.gitignore** to prevent exposing your credentials, especially if you're using a version control system.

    ## Step 1: Upload an Encrypted File
    
    Set up a script, **upload.js**, in your project directory. Add the following code:
    
    ```jsx
    import * as dotenv from 'dotenv';
    dotenv.config();
    import { ethers } from "ethers";
    import lighthouse from '@lighthouse-web3/sdk';
    
    const signAuthMessage = async (publicKey, privateKey) => {
      const provider = new ethers.JsonRpcProvider();
      const signer = new ethers.Wallet(privateKey, provider);
      const messageRequested = (await lighthouse.getAuthMessage(publicKey)).data.message;
      const signedMessage = await signer.signMessage(messageRequested);
      return signedMessage;
    }
    
    const deployEncrypted = async () => {
      const path = "Absolute/path/to/your/file.txt"; // Update this path
      const apiKey = process.env.API_KEY;
      const publicKey = "Your_Public_Key"; // Update this
      const privateKey = process.env.PRIVATE_KEY;
      const signedMessage = await signAuthMessage(publicKey, privateKey);
    
      const response = await lighthouse.uploadEncrypted(
        path,
        apiKey,
        publicKey,
        signedMessage
      );
    
      console.log(response);
    }
    
    deployEncrypted();
    ```
    
    **Run the script:**
    
    ```bash
    node upload.js
    ```
    
    **Expected Response:**
    
    ```bash
    {
      data: [
        {
          Name: 'test.txt',
          Hash: 'ENCRYPTED_CID',
          Size: '58'
        }
      ]
    }
    ```
    
    ## Step 2: Apply Access Control Condition:
    
    Create a script, **access-control.js**, with the following:
    
    ```jsx
    import * as dotenv from 'dotenv';
    dotenv.config();
    import { ethers } from "ethers";
    import lighthouse from '@lighthouse-web3/sdk';
    
    const signAuthMessage = async (publicKey, privateKey) => {
      const provider = new ethers.JsonRpcProvider();
      const signer = new ethers.Wallet(privateKey, provider);
      const messageRequested = (await lighthouse.getAuthMessage(publicKey)).data.message;
      const signedMessage = await signer.signMessage(messageRequested);
      return signedMessage;
    }
    
    const accessControl = async () => {
    	try{  
    		const cid = "Your_File_CID"; 
    		// Update this with the CID from the previous step
    		const publicKey = "Your_Public_Key"; // Update this
    	  const privateKey = process.env.PRIVATE_KEY;
    
      const conditions = [
        {
          id: 1,
          chain: "Optimism",
          method: "getBlockNumber",
    			standardContractType: "",
          returnValueTest: { comparator: ">", value: "Your_Block_Number" }, // Update this value as per your requirements
        },
      ];
    
    // Aggregator is what kind of operation to apply to access conditions
        // Suppose there are two conditions then you can apply ([1] and [2]), ([1] or [2]), !([1] and [2]).
    
      const aggregator = "([1])";
    
      const signedMessage = await signAuthMessage(publicKey, privateKey);
    
      const response = await lighthouse.applyAccessCondition(
        publicKey,
        cid,
        signedMessage,
        conditions,
        aggregator
      );
    
      console.log(response);
    }
    
    accessControl();
    
    ```
    
    **Execute the script:**
    
    ```bash
    node access-control.js
    ```
    
    **Expected Response:**
    
    ```bash
    {
      data: {
        cid: 'ENCRYPTED_CID',
        status: 'Success'
      }
    }
    ```
    
    **Note:**
    
    - Only the owner of the file can apply access conditions
    - This only works when file is uploaded with lighthouse encryption
    
    ## (Optional) Step 3: Retrieve Access Control Conditions:
    
    Formulate another script, **get-conditions.js**, as:
    
    ```jsx
    import lighthouse from '@lighthouse-web3/sdk';
    
    const accessConditions = async() => {
      const cid = "Your_File_CID"; // Update this
      const response = await lighthouse.getAccessConditions(cid);
      console.log("Condition:", response.data.conditions);
    	console.log("Response:", response)
    }
    
    accessConditions();
    ```
    
    **Run the script:**
    
    ```bash
    node get-conditions.js
    ```
    
    **Expected Response:**
    
    ```bash
    Condition: [
      {
        id: 1,
        chain: 'Optimism',
        method: 'getBlockNumber',
        standardContractType: '',
        returnValueTest: { comparator: '>', value: 'Your_Block_Number' }
      }
    ]
    Response: {
      data: {
        aggregator: '[1]',
        conditions: [ [Object] ],
        conditionsSolana: [],
        sharedTo: [],
        owner: 'Your_Public_Key',
        cid: 'ENCRYPTED_CID'
      }
    }
    ```
    
    ## (Receiver side) Step 4: Verify Access and Retrieve Encryption Key:
    
    Once you've uploaded a file and set an access control condition, before attempting to download or decrypt it, you might want to check if you have the necessary permissions (or if the conditions have been met). This step will guide you on how to do just that:
    
    **Prepare Your Script**:
    
    Create a new script named **verify-access.js** in your project directory. Insert the following code:
    
    ```jsx
    import * as dotenv from 'dotenv';
    dotenv.config();
    import { ethers } from "ethers";
    import lighthouse from '@lighthouse-web3/sdk';
    
    const signAuthMessage = async (publicKey, privateKey) => {
      const provider = new ethers.JsonRpcProvider();
      const signer = new ethers.Wallet(privateKey, provider);
      const messageRequested = (await lighthouse.getAuthMessage(publicKey)).data.message;
      const signedMessage = await signer.signMessage(messageRequested);
      return signedMessage;
    }
    
    const getFileEncryptionKey = async () => {
      try {
        const cid = 'ENCRYPTED_CID'; // Replace with your CID
        const publicKey = 'Receiver_side_public_key'; // Replace with your public key
        const privateKey = process.env.RECEIVER_SIDE_PRIVATE_KEY;
    
        const signedMessage = await signAuthMessage(publicKey, privateKey);
    
        const keyResponse = await lighthouse.fetchEncryptionKey(
          cid,
          publicKey,
          signedMessage
        );
    
        // Print the direct response
        console.log(keyResponse);
    
      } catch (error) {
        console.log("Error:", error.message);
      }
    }
    
    getFileEncryptionKey();
    ```
    
    **Run the Script**:
    
    Execute the **verify-access.js** script:
    
    ```bash
    node verify-access.js
    ```
    
    **Expected Response (When you have access):**
    
    ```bash
    {
      data: {
        key: 'KEY'
      }
    }
    ```
    
    ****************************************Expected Response (When you do not have access):****************************************
    
    ```bash
    { message: "you don't have access", data: {} }
    ```

## Introduction to Secure File Sharing with Lighthouse SDK

In the realm of decentralized technology and applications, ensuring secure and efficient file-sharing has always been a top priority. Lighthouse, a notable player in this domain, has developed a robust SDK that aids developers in achieving this. This SDK leverages blockchain principles and IPFS, which stands for InterPlanetary File System, to ensure that files shared across networks are not only secure but also immutable and tamper-proof.

## Why is this important?

In traditional file-sharing systems, there's a central server where files are stored. This poses several challenges: from server downtimes to the risk of central point failures and vulnerabilities. IPFS and blockchain, as adopted by Lighthouse, circumvent these challenges by storing files across a network, ensuring redundancy and security.

Moreover, with the increasing emphasis on privacy and data protection regulations worldwide, tools like the Lighthouse SDK empower developers to build applications that prioritize user data security. By using encryption and decentralized storage, we can ensure that our users' files remain confidential, accessible only by intended recipients.

## What will you learn in this tutorial?

This tutorial will guide you step-by-step on how to integrate the Lighthouse SDK into your Node.js application. By the end, you'll be able to securely share encrypted files with specified recipients, leveraging Lighthouse's decentralized storage and Ethereum's robust authentication mechanisms. Whether you're a seasoned developer or just starting out in the world of decentralized apps, this guide aims to make the process straightforward and intuitive.

Let's get started by setting the foundation for our file-sharing application!

## Preparation:

### Prerequisites:

- Ensure you have Node.js installed. If not, **[download it here](https://nodejs.org/en/download/)**.

### 1. Set Up Lighthouse SDK and Wallet:

- Install the SDK globally:
    
    ```bash
    npm install -g @lighthouse-web3/sdk
    ```
    
- Generate a new Lighthouse wallet. Safeguard the provided **`Public Key`** and **`Private Key`**:
    
    ```bash
    lighthouse-web3 create-wallet
    ```
    

### 2. Project Environment Configuration:

- Create and navigate to a new directory for your endeavor:
    
    ```bash
    mkdir lighthouse-encryption && cd lighthouse-encryption
    ```
    
- Commence a new Node.js project:
    
    ```bash
    npm init -y
    ```
    
- Install the necessary local packages:
    
    ```bash
    npm install dotenv ethers
    ```
    

### 3. Enhancing Security:

- Generate a **`.env`** file within your project directory.
- Populate **`.env`** with your Lighthouse private key:
    
    ```makefile
    PRIVATE_KEY=Your_Private_Key
    ```
    
- To maintain security, add **`.env`** to your **`.gitignore`** file, especially vital if using a version control platform.

---

## Implementation:

### **1. Setting the Groundwork:**

Within your project directory:

- Construct a file named **`fileSharing.js`**.

### **2. Import and Initialization:**

In **`fileSharing.js`**, write:

```jsx
import * as dotenv from 'dotenv';
dotenv.config();
import { ethers } from "ethers";
import lighthouse from '@lighthouse-web3/sdk';
```

### **3. Message Signing Function:**

This helper function will assist in the authentication process:

```jsx
const signAuthMessage = async (publicKey, privateKey) => {
  const provider = new ethers.JsonRpcProvider();
  const signer = new ethers.Wallet(privateKey, provider);
  const messageRequested = (await lighthouse.getAuthMessage(publicKey)).data.message;
  const signedMessage = await signer.signMessage(messageRequested);
  return signedMessage;
}
```

### **4. File Sharing Procedure:**

Implement the function to handle file sharing via Lighthouse SDK

*To ensure clarity and simplicity, let's break down the file sharing procedure into three distinct points:*

### **4.1 Initialize Variables:**

Set up the fundamental variables required for our function. Each variable holds specific data crucial for the operation:

```jsx
const cid = "QmS2NzycJoA7De33qMWwqyE2w3BL1i396qfwZiHBb1KuZh";
// CID: Unique identifier for content on IPFS.

const publicKey = "0x5D62F371206306F1ebd4573803F70772f1153186";
// PublicKey: Your Lighthouse identity.

const privateKey = process.env.PRIVATE_KEY;
// PrivateKey: Secured key for authentication, stored away from the codebase.

const receiverPublicKey = ["0xea447D81825282D3ec02772f1ab045ec6227F3e4"];
// ReceiverPublicKey: Intended recipient's Lighthouse identity.

```

### **4.2 Authenticate and Sign the Message:**

With our variables set, the next step is to authenticate our actions by signing the message:

```jsx
const signedMessage = await signAuthMessage(publicKey, privateKey);
// SignedMessage: A verified authentication message for security.
```

### **4.3 Share the File:**

Having our signed message and our initialized variables, we're ready to share our encrypted file securely:

```jsx
const shareResponse = await lighthouse.shareFile(
  publicKey,
  receiverPublicKey,
  cid,
  signedMessage
);
// ShareFile: Lighthouse function to securely share your file.

console.log(shareResponse);
// ResponseOutput: Shows the result of the file-sharing action.

// To view the shared file, navigate to:
// https://files.lighthouse.storage/viewFile/<cid>
```

In the event of an error or an issue during this process, the catch block will capture and display it for our reference:

```jsx
} catch (error) {
    console.log(error);
}
```

Lastly, initiate the function:

```jsx
shareFile();
```

### **Full Code for Secure File Sharing using Lighthouse SDK:**

```jsx
import * as dotenv from 'dotenv';
dotenv.config();
import { ethers } from "ethers";
import lighthouse from '@lighthouse-web3/sdk';

const signAuthMessage = async (publicKey, privateKey) => {
  const provider = new ethers.JsonRpcProvider();
  const signer = new ethers.Wallet(privateKey, provider);
  const messageRequested = (await lighthouse.getAuthMessage(publicKey)).data.message;
  const signedMessage = await signer.signMessage(messageRequested);
  return signedMessage;
};

const shareFile = async () => {
  try {
    const cid = "QmS2NzycJoA7De33qMWwqyE2w3BL1i396qfwZiHBb1KuZh";
    // CID: Unique identifier for content on IPFS.

    const publicKey = "0x5D62F371206306F1ebd4573803F70772f1153186";
    // PublicKey: Your Lighthouse identity.

    const privateKey = process.env.PRIVATE_KEY;
    // PrivateKey: Secured key for authentication, stored away from the codebase.

    const signedMessage = await signAuthMessage(publicKey, privateKey);
    // SignedMessage: A verified authentication message for security.

    const receiverPublicKey = ["0xea447D81825282D3ec02772f1ab045ec6227F3e4"];
    // ReceiverPublicKey: Intended recipient's Lighthouse identity.

    const shareResponse = await lighthouse.shareFile(
      publicKey,
      receiverPublicKey,
      cid,
      signedMessage
    );
    // ShareFile: Lighthouse function to securely share your file.

    console.log(shareResponse);
    // ResponseOutput: Shows the result of the file-sharing action.

    // Navigate to view the shared file:
    // https://files.lighthouse.storage/viewFile/<cid>
  } catch (error) {
    console.log(error);
  }
};

shareFile();
```

### **5. Running the Script:**

Execute the script:

```bash
node fileSharing.js
```

Observe the file-sharing response and ensure you can access the CID link to validate the secure file sharing.

## Wrap-Up:

Congratulations! You've adeptly shared an encrypted file using the Lighthouse SDK. Always prioritize the security of your private and API keys.

# **Introduction**

In the realm of decentralized applications (dApps), user authentication remains a critical aspect. Traditional methods often rely on centralized servers, which can be a point of vulnerability. Enter Passkey: a decentralized authentication method that leverages the power of WebAuthn and Ethereum.

**What is Passkey?**

Passkey is a concept where users can authenticate themselves using cryptographic keys instead of traditional usernames and passwords. By integrating WebAuthn, a web standard for secure authentication, with Ethereum, a decentralized blockchain platform, Passkey offers a robust and secure authentication mechanism for dApps.

In this guide, we'll walk you through creating a demo app that showcases this integration using `create-react-app`.

## Use cases

Before jumping onto the tutorial, let us look at some use cases for a passkey type encryption on the decentralized web. **The use cases ranges all the way from:**

- Decentralized Social Media
- DeFi Applications
- Healthcare Record Management

**To more general application like:**

- Website and Application Authentication
- Multi-Factor Authentication (MFA)
- Secure Document Access

Basically anything that needs frequent signing for authentication can make use of Lighthouse Passkey authentication. 

### **Prerequisites**

Ensure you have Node.js and npm installed. If not, download and install them from [Node.js official website](https://nodejs.org/).

### **Setting Up**

1. First, let's create a new React app:

```bash
npx create-react-app passkey-demo
cd passkey-demo
```

1. Install the necessary packages:

```bash
npm install axios
```

### **Utility Functions**

These functions will aid in the authentication process:

1. **Fetching Authentication Message**

```jsx
const getAuthMessage = async (address) => {
  try {
    const data = await axios
      .get(`https://encryption.lighthouse.storage/api/message/${address}`, {
        headers: {
          "Content-Type": "application/json",
        },
      })
      .then((res) => res.data[0].message);
    return { message: data, error: null };
  } catch (err) {
    return { message: null, error: err?.response?.data || err.message };
  }
};
```

1. **Buffer and Base64 Conversions**

```jsx
function bufferToBase64url(buffer) {
  const byteView = new Uint8Array(buffer);
  let str = "";
  for (const charCode of byteView) {
    str += String.fromCharCode(charCode);
  }

  // Binary string to base64
  const base64String = btoa(str);

  // Base64 to base64url
  // We assume that the base64url string is well-formed.
  const base64urlString = base64String
    ?.replace(/\+/g, "-")
    ?.replace(/\//g, "_")
    ?.replace(/=/g, "");
  return base64urlString;
}

function base64urlToBuffer(base64url) {
  let binary = atob(base64url?.replace(/_/g, "/")?.replace(/-/g, "+"));
  let length = binary.length;
  let buffer = new Uint8Array(length);

  for (let i = 0; i < length; i++) {
    buffer[i] = binary.charCodeAt(i);
  }

  return buffer;
}

```

1. **Transforming Public Key**

```jsx
function transformPublicKey(publicKey) {
  const selected_key_index = 0;
  let transformedPublicKey = {
    ...publicKey,
    challenge: new Uint8Array([...publicKey.challenge.data]),
    allowCredentials: [
      {
        type: "public-key",
        id: base64urlToBuffer(
          publicKey.allowCredentials[selected_key_index]?.credentialID
        ),
      },
    ],
  };

  return [
    transformedPublicKey,
    publicKey.allowCredentials[selected_key_index]?.credentialID,
  ];
}

```

### **The Main App**

Our main React component will handle user interactions:

```jsx
import React, { useState } from "react";
import axios from "axios";
import "./App.css";

function App() {
  // State variables for account, error, chain ID, keys, and token
  const [account, setAccount] = useState("");
  const [error, setError] = useState("");
  const [chainId, setChainId] = useState("");
  const [keys, setKeys] = useState({});
  const [token, setToken] = useState("");

  // Function to connect to the Ethereum wallet
  const connectWallet = async () => {
    if (window.ethereum) {
      try {
        // Request account access
        const accounts = await window.ethereum.request({
          method: "eth_requestAccounts",
        });
        setAccount(accounts[0]);
        const chainId = await window.ethereum.request({
          method: "eth_chainId",
        });
        setChainId(chainId);
      } catch (error) {
        console.error("User denied account access");
      }
    } else {
      console.error("Ethereum provider not detected");
    }
  };

  // Function to disconnect from the Ethereum wallet
  const disconnect = () => {
    setAccount("");
    setChainId("");
  };

  // Function to sign a message using the Ethereum wallet
  const signMessage = async (message) => {
    try {
      const signature = await window.ethereum.request({
        method: "personal_sign",
        params: [account, message],
      });
      return signature;
    } catch (error) {
      setError(error.toString());
    }
  };

  // Convert account to lowercase for uniformity
  const username = account.toLowerCase();

  // Function to login using Passkey
  const login = async () => {
    try {
      const startResponse = await axios.post(
        "https://encryption.lighthouse.storage/passkey/login/start",
        {
          address: username,
        }
      );
      const publicKey = startResponse.data;
      const [transformedPublicKey, credentialID] = transformPublicKey(publicKey);

      // Get credentials using WebAuthn
      const credential = await navigator.credentials.get({
        publicKey: transformedPublicKey,
      });

      // Convert credential to a format suitable for the backend
      const serializeable = {
        authenticatorAttachment: credential.authenticatorAttachment,
        id: credential.id,
        rawId: bufferToBase64url(credential.rawId),
        response: {
          attestationObject: bufferToBase64url(credential.response.attestationObject),
          clientDataJSON: bufferToBase64url(credential.response.clientDataJSON),
          signature: bufferToBase64url(credential.response.signature),
          authenticatorData: bufferToBase64url(credential.response.authenticatorData),
        },
        type: credential.type,
      };

      const finishResponse = await axios.post(
        "https://encryption.lighthouse.storage/passkey/login/finish",
        {
          credentialID,
          data: credential,
        }
      );
      const token = finishResponse.data.token;
      setToken(token);
      if (token) {
        alert("Successfully authenticated using webAuthn");
      }
    } catch (error) {
      console.error("Error during login:", error);
    }
  };

  // Function to register using Passkey
  const register = async () => {
    try {
      const { message } = await getAuthMessage(account.toLowerCase());
