尝试解密使用密码短语保护的私钥

Question

我尝试使用加密nodejs模块。但我没有成功地使它工作。

import * as crypto from 'crypto';
import { RsaPrivateKey } from 'crypto';
const privateKey = crypto.privateDecrypt(rsaPrivateKey, Buffer.from('')).toString();

我有一个密码短语。我需要这样做，以便在AWS中导入我的证书。有人有主意吗?

我知道我们可以在golang中使用

if x509.IsEncryptedPEMBlock(block) {
der, wrongPass := x509.DecryptPEMBlock(block, []byte(o.passphrase))

-----BEGIN RSA PRIVATE KEY-----
Proc-Type: 4,ENCRYPTED
DEK-Info: AES-256-CBC,XXXXXXXXX

Answer 1

解密很容易实现，使用NodeJS的加密模块使用两个函数crypto.createPrivateKey()导入加密密钥和keyObject.export()导出未加密密钥:

crypto = require('crypto');
encryptedPkcs1 = `-----BEGIN RSA PRIVATE KEY-----
Proc-Type: 4,ENCRYPTED
DEK-Info: AES-256-CBC,B2FBBDCE627586CB04423335D9D4EC59

-----END RSA PRIVATE KEY-----`
encryptedKey = crypto.createPrivateKey({
key: encryptedPkcs1,
passphrase: 'myPassword'})
decryptedKey = encryptedKey.export({
format: 'pem',
type: 'pkcs1',})

请注意，在实践中，现在的密钥不应该小于2048位出于安全原因。这里的512位密钥仅用于测试。

输出为:

-----BEGIN RSA PRIVATE KEY-----
