ECDH 类
ECDH
类是用于创建椭圆曲线 Diffie-Hellman (ECDH) 密钥交换的实用工具。
可以使用 crypto.createECDH()
函数创建 ECDH
类的实例。
const crypto = require('crypto');
const assert = require('assert');
// 生成 Alice 的密钥...
const alice = crypto.createECDH('secp521r1');
const aliceKey = alice.generateKeys();
// 生成 Bob 的密钥...
const bob = crypto.createECDH('secp521r1');
const bobKey = bob.generateKeys();
// 交换并生成密钥...
const aliceSecret = alice.computeSecret(bobKey);
const bobSecret = bob.computeSecret(aliceKey);
assert.strictEqual(aliceSecret.toString('hex'), bobSecret.toString('hex'));
// OK
The ECDH
class is a utility for creating Elliptic Curve Diffie-Hellman (ECDH)
key exchanges.
Instances of the ECDH
class can be created using the
crypto.createECDH()
function.
const crypto = require('crypto');
const assert = require('assert');
// Generate Alice's keys...
const alice = crypto.createECDH('secp521r1');
const aliceKey = alice.generateKeys();
// Generate Bob's keys...
const bob = crypto.createECDH('secp521r1');
const bobKey = bob.generateKeys();
// Exchange and generate the secret...
const aliceSecret = alice.computeSecret(bobKey);
const bobSecret = bob.computeSecret(aliceKey);
assert.strictEqual(aliceSecret.toString('hex'), bobSecret.toString('hex'));
// OK
