What is @stablelib/x25519?

@stablelib/x25519 is a JavaScript library that provides cryptographic functions for performing X25519 key exchange operations. It is part of the StableLib collection of cryptographic libraries, which are designed to be secure, fast, and easy to use.

What are @stablelib/x25519's main functionalities?

Generate Key Pair

This feature allows you to generate a new X25519 key pair, which includes a public key and a private key.

const { generateKeyPair } = require('@stablelib/x25519');
const keyPair = generateKeyPair();
console.log(keyPair);

Compute Shared Secret

This feature allows you to compute a shared secret using your private key and the other party's public key. This shared secret can be used for secure communication.

const { generateKeyPair, sharedKey } = require('@stablelib/x25519');
const aliceKeyPair = generateKeyPair();
const bobKeyPair = generateKeyPair();
const sharedSecret = sharedKey(aliceKeyPair.secretKey, bobKeyPair.publicKey);
console.log(sharedSecret);
