Encryption / Decryption

Encrypt endpoint

• Endpoint: POST /api/services/encrypt

• Parameters: The body of the request should contain a binary application/octet-stream.

• Purpose: This endpoint is used to encrypt a document. It accepts binary data and returns an encrypted bytes string.

• Responses:

  • 200: This is a successful HTTP response code. It returns a bytes string containing the encrypted document. For example: b'0x04b2bfab1f4e...7ed0573'

Example response:

Javascript Example

Decrypt endpoint

• Endpoint: POST /api/services/decrypt

• Parameters: The body of the request should contain a JSON object with the following properties:

  • decrypterAddress: A string containing the address of the decrypter (required).

  • chainId: The chain ID of the network the document is on (required).

  • transactionId: The transaction ID of the encrypted document (optional).

  • dataNftAddress: The address of the data non-fungible token (optional).

  • encryptedDocument: The encrypted document (optional).

  • flags: The flags of the encrypted document (optional).

  • documentHash: The hash of the encrypted document (optional).

  • nonce: The nonce of the encrypted document (required).

  • signature: The signature of the encrypted document (required).

• Purpose: This endpoint is used to decrypt a document. It accepts the decrypter address, chain ID, and other optional parameters, and returns the decrypted document.

• Responses:

  • 200: This is a successful HTTP response code. It returns a bytes string containing the decrypted document.

Javascript Example

const axios = require('axios');

async function decryptAsset(payload) {
    // Define the base URL of the services.
    const SERVICES_URL = "<BASE URL>"; // Replace with your base services URL.

    // Define the endpoint.
    const endpoint = `${SERVICES_URL}/api/services/decrypt`;

    try {
        // Send a POST request to the endpoint with the payload in the request body.
        const response = await axios.post(endpoint, payload);

        // Check the response.
        if (response.status !== 200) {
            throw new Error(`Response status code is not 200: ${response.data}`);
        }

        // Use the response data here.
        console.log(response.data);

    } catch (error) {
        console.error(error);
    }
}

// Define the payload.
let payload = {
    "decrypterAddress": "<DECRYPTER ADDRESS>", // Replace with your decrypter address.
    "chainId": "<CHAIN ID>", // Replace with your chain ID.
    "transactionId": "<TRANSACTION ID>", // Replace with your transaction ID.
    "dataNftAddress": "<DATA NFT ADDRESS>", // Replace with your Data NFT Address.
};

// Run the function.
decryptAsset(payload);
