What is @stablelib/ed25519?
@stablelib/ed25519 is a JavaScript library for Ed25519 public-key signature system. It provides functionalities for key generation, signing messages, and verifying signatures. The library is part of the StableLib collection, which is known for its focus on security and performance.
What are @stablelib/ed25519's main functionalities?
Key Generation
This feature allows you to generate a new Ed25519 key pair. The `generateKeyPair` function returns an object containing a `publicKey` and a `secretKey`.
const { generateKeyPair } = require('@stablelib/ed25519');
const keyPair = generateKeyPair();
console.log('Public Key:', keyPair.publicKey);
console.log('Secret Key:', keyPair.secretKey);
Signing Messages
This feature allows you to sign a message using a secret key. The `sign` function takes a secret key and a message, and returns the signature.
const { sign } = require('@stablelib/ed25519');
const message = new Uint8Array([1, 2, 3, 4, 5]);
const signature = sign(keyPair.secretKey, message);
console.log('Signature:', signature);
Verifying Signatures
This feature allows you to verify a signature using a public key. The `verify` function takes a public key, a message, and a signature, and returns a boolean indicating whether the signature is valid.
const { verify } = require('@stablelib/ed25519');
const isValid = verify(keyPair.publicKey, message, signature);
console.log('Is the signature valid?', isValid);
