AEZ implementation for node
The current version passes all test vectors generated with this hacked version of aez. But the author does not give any guarantees that the algorithm is implemented correctly for every edge case!
How to install
npm install --save aez
yarn add aez
How to use
NOTE: Every parameter that is not a number should be of type
Buffer (or array of
const aez = ;const Buffer = Buffer;const key = Buffer; // sha256 of 'my-secret-key', but you should use a key derivation function like scrypt or PBKDF2!const salt = Buffer; // some random saltconst plaintext = Buffer;const tau = 4;const cipherText = aez;console;const decryptedText = aez;console;
aez.encrypt(key : Buffer, nonce : Buffer, additionalData : Buffer, tau : Number, plaintext : Buffer) : Buffer
Encrypts a plaintext buffer with the given key, nonce and additionalData.
aez.decrypt(key : Buffer, nonce : Buffer, additionalData : Buffer, tau : Number, ciphertext : Buffer) : Buffer
Decrypts a ciphertext buffer with the given key, nonce and additionalData.
If the key is incorrect,
null is returned.
The code is not yet optimized for performance.
