The DiffieHellman
class is a utility for creating Diffie-Hellman key exchanges.
Instances of the DiffieHellman
class can be created using the createDiffieHellman function.
import assert from 'node:assert';
const {
createDiffieHellman,
} = await import('node:crypto');
// Generate Alice's keys...
const alice = createDiffieHellman(2048);
const aliceKey = alice.generateKeys();
// Generate Bob's keys...
const bob = createDiffieHellman(alice.getPrime(), alice.getGenerator());
const bobKey = bob.generateKeys();
// Exchange and generate the secret...
const aliceSecret = alice.computeSecret(bobKey);
const bobSecret = bob.computeSecret(aliceKey);
// OK
assert.strictEqual(aliceSecret.toString('hex'), bobSecret.toString('hex'));
