Data should be accessible by the owner of the private key. The decrypt() function allows applications to decrypt any piece of data encrypted with the user's private key, similarly to the .

Argument
Type
Description

data

The encrypted data to be decrypted with the user's private key

algorithm

An object specifying the algorithm to be used and any extra parameters if required

Note: This function requires the permission.

Example usage

// connect to the extension
await window.arweaveWallet.connect(["ENCRYPT", "DECRYPT"]);

// encrypt data using RSA-OAEP
const encrypted = await arweaveWallet.encrypt(
    new TextEncoder().encode("This message will be encrypted"),
    { name: "RSA-OAEP" }
);

console.log("Encrypted bytes:", encrypted);

// now decrypt the same data using
// the same algorithm
const decrypted = await arweaveWallet.decrypt(
    encrypted,
    { name: "RSA-OAEP" }
);

console.log(
    "Decrypted data:",
    new TextDecoder().decode(decrypted)
);

Old (deprecated) usage

// connect to the extension
await window.arweaveWallet.connect(["ENCRYPT", "DECRYPT"]);

// encrypt data
const encrypted = await window.arweaveWallet.encrypt(
  new TextEncoder().encode("This message will be encrypted"),
  {
    algorithm: "RSA-OAEP",
    hash: "SHA-256",
  }
);

console.log("Encrypted bytes:", encrypted);

// decrypt data
const decrypted = await window.arweaveWallet.decrypt(
  encrypted,
  {
    algorithm: "RSA-OAEP",
    hash: "SHA-256",
  }
);

console.log("Decrypted data:", new TextDecoder().decode(decrypted));
