我正在尝试使用node-jose
实现简单的JOSE
encrypt
和decrypt
函数。
我的代码如下(使用Node 8.2.1编写)
const { JWE } = require('node-jose');
const jose = (publicKey, privateKey) => {
async function encrypt(raw) {
if (!raw) throw new Error('Missing raw data.')
const buffer = new Buffer(JSON.stringify(raw));
return JWE.createEncrypt(publicKey).update(buffer).final();
}
async function decrypt(encrypted) {
if (!encrypted) throw new Error('Missing encrypted data.')
const buffer = new Buffer(JSON.stringify(encrypted));
return JWE.createDecrypt(privateKey).decrypt(buffer);
}
return { encrypt, decrypt }
}
module.exports = jose;
我使用generate-rsa-keypair
生成RSA密钥对。
因此,通过此代码进行测试,加密方面的工作正常
const { JWK } = require('node-jose');
const keygen = require('generate-rsa-keypair');
const jose = require('./src/utils/jose');
const rawKeys = keygen();
const makeKey = pem => JWK.asKey(pem, 'pem');
async function start() {
const publicKey = await makeKey(rawKeys.public)
const privateKey = await makeKey(rawKeys.private)
const raw = {
iss: 'test',
exp: new Date().getTime() + 3600,
sub: {
test: 'This is a test',
},
};
const { encrypt, decrypt } = jose(publicKey, privateKey);
return encrypt(raw).then(encrypted => decrypt(encrypted));
}
return start().then((result) => {
console.log('decrypted', result)
}, (err) => {
console.error(err);
});
encrypted
结果
{
recipients: [ { encrypted_key: 'ciNiK6Unq30zCAXxIl2Dx9b8bZAi79qbpL1yUCwTFnSghFLrIZ11_D2ozt5on3r3ThUu96oDLZPcNShbqWPMV49NvQAsSNGdemhgzmTt3Lf3rJn1YiqvJvqf5NIXdmzjdoEZi-d9224mGpZGVKtIIFeT6-0hYgm5zNqq_aF_X2jy5IiF-mAGspNdXIk_KXPrTVbnU-XL9J5aAoG2Lp51Te1WzGA4Fjg4Ve5ZTzH6TLlQ5R5Ob_14liK-INrSi3armwXrtMgJcTmI_4oBtORtZp8AjaXzecFO_GzifvRVCSKx2vmpy9KaECpskMhZBHVx9RX9cvGKh7hq3Y7vsUucZw' } ],

tag: 'z8nwrJfRgOi1hYMBI9lGeQ'
}
但是当我尝试解密时,我得到了
Error: no key found
at processKey (node_modules/node-jose/lib/jwe/decrypt.js:157:22)
使用node-jose
的例子很少,所以我不确定以下
decrypt
,但可能情况并非如此。这是如何运作的?
答案 0 :(得分:0)
使用公钥/私钥对时,private
密钥用于解密,public
密钥用于加密。
JWEDecrypter.decrypt()
的输入是JWEEncrypter.final()
的承诺输出。
将decrypt
功能更改为:
async function decrypt(encrypted) {
if (!encrypted) throw new Error('Missing encrypted data.')
return JWE.createDecrypt(privateKey).decrypt(encrypted);
}
