ecdh/examples/keys.js

Native node.js module for ECDH and ECDSA

var ecdh = require("../index");

// Pick some curve
var curve = ecdh.getCurve("secp128r1"),
  // Generate random key
  privateKey = ecdh.PrivateKey.generate(curve),
  // generate public key from private key
  publicKey = privateKey.derivePublicKey();

// Or you may get the key from a buffer:
// privateKey = ecdh.PrivateKey.fromBuffer(curve, buf2);

console.log("private key length:", privateKey.buffer.length);
console.log("private key:", privateKey.buffer.toString("hex"));
console.log("public key length:", publicKey.buffer.length);
console.log("public key:", publicKey.buffer.toString("hex"));
