X25519

Utilities for working with X25519 elliptic curve Diffie-Hellman key agreement.

X25519 is a high-performance elliptic curve that can be used to perform Diffie-Hellman key agreement to derive shared secrets between parties. It is designed for use with the elliptic curve Diffie-Hellman (ECDH) key agreement scheme.

Examples

Below are some examples demonstrating common usages of the X25519 module:

• Creating Key Pairs

• Deriving Shared Secrets

Creating Key Pairs

import { X25519 } from 'ox'
 
const { privateKey, publicKey } = X25519.createKeyPair()

Deriving Shared Secrets

import { X25519 } from 'ox'
 
const { privateKey: privateKeyA } = X25519.createKeyPair()
const { publicKey: publicKeyB } = X25519.createKeyPair()
 
const sharedSecret = X25519.getSharedSecret({
  privateKey: privateKeyA,
  publicKey: publicKeyB
})
