js实现rsa算法

npm install jsencrypt --save

const JSEncrypt = require('jsencrypt').default;

// 创建JSEncrypt实例
const crypt = new JSEncrypt();

// 设置公钥和私钥
const publicKey = `-----BEGIN PUBLIC KEY-----
...
-----END PUBLIC KEY-----`; // 公钥内容
const privateKey = `-----BEGIN RSA PRIVATE KEY-----
...
-----END RSA PRIVATE KEY-----`; // 私钥内容

crypt.setPublicKey(publicKey);
crypt.setPrivateKey(privateKey);

// 要加密的数据
const data = 'Hello, RSA!';

// 加密
const encryptedData = crypt.encrypt(data);
console.log('Encrypted Data:', encryptedData);

// 解密
const decryptedData = crypt.decrypt(encryptedData);
console.log('Decrypted Data:', decryptedData);

const NodeRSA = require('node-rsa');

// 生成密钥对
const key = new NodeRSA({ b: 512 }); // 512位密钥，实际应用中建议使用更长的密钥，如2048位

const publicKey = key.exportKey('public');
const privateKey = key.exportKey('private');

console.log('Public Key:', publicKey);
console.log('Private Key:', privateKey);
