似乎有一种简单的方法可以做到这一点。有一个包叫cryptico
那可以做的事情。
首先安装包:
npm i cryptico
示例
const cryptico = require('cryptico');
const PassPhrase = "The Moon is a Harsh Mistress.";
// The length of the RSA key, in bits.
const Bits = 1024;
const RSAkey = cryptico.generateRSAKey(PassPhrase, Bits);
const PublicKeyString = cryptico.publicKeyString(RSAkey);

更新
因此,如果您需要ASYMMETRIC 加密(据我所知,这适用于一对称为publickey 和privatekey 的密钥),您可以简单地使用纯Node.js 实现。
示例
const { generateKeyPairSync, publicEncrypt, privateDecrypt } = require('crypto');
const PassPhrase = "The Moon is a Harsh Mistress.";
const Bits = 1024;
const encryptWithRSA = (input, publickey) => {
const buffer = Buffer.from(input, 'utf-8');
const encrypted = publicEncrypt(publicKey, buffer);
return encrypted.toString("base64");
}
const decryptWithRSA = function (input, privatekey) {
const buffer = Buffer.from(input, 'base64');
const decrypted = privateDecrypt(
{
key: privatekey,
passphrase: PassPhrase,
},
buffer,
)
return decrypted.toString("utf8");
};
const { privateKey, publicKey } = generateKeyPairSync('rsa', {
modulusLength: Bits,
publicKeyEncoding: {
type: 'spki',
format: 'pem'
},
privateKeyEncoding: {
type: 'pkcs8',
format: 'pem',
cipher: 'aes-256-cbc',
passphrase: PassPhrase
}
});
const encrypted = encryptWithRSA('yes i know', publicKey)
console.log(encrypted);
console.log(decryptWithRSA(encrypted, privateKey));
输出(encrypted 值是随机的,如您所知)
