尝试解密 aes-256-cbc 时不断出现“无效的初始化向量”错误

Question

所以我有一个端点，我必须在其中解密密钥，并根据信息返回一些数据或不返回一些数据。问题是我总是得到这个错误：

TypeError: Invalid initialization vector
    at Decipheriv.createCipherBase (node:internal/crypto/cipher:116:19)
    at Decipheriv.createCipherWithIV (node:internal/crypto/cipher:135:3)
    at new Decipheriv (node:internal/crypto/cipher:289:3)
    at createDecipheriv (node:crypto:146:10)

这是我解密的功能。 Salt 和 IV 在密码的开头连接在一起。

import {
  createDecipheriv,
  pbkdf2Sync,
  randomBytes,
  createCipheriv,
} from 'crypto';

const keySize = 256;
const derivationIterations = 1000;

decrypt(cipherText: string, passPhrase: string): string {
    // Get the complete stream of bytes that represent:
    // [32 bytes of Salt] + [32 bytes of IV] + [n bytes of CipherText]
    const cipherTextBytesWithSaltAndIv = Buffer.from(cipherText, 'base64');

    // Get the saltbytes by extracting the first 32 bytes from the supplied cipherText bytes.
    const saltStringBytes = cipherTextBytesWithSaltAndIv.slice(
      0,
      this.keySize / 8,
    );

    // Get the IV bytes by extracting the next 32 bytes from the supplied cipherText bytes.
    const ivStringBytes = cipherTextBytesWithSaltAndIv.slice(
      this.keySize / 8,
      (this.keySize / 8) * 2,
    );

    // Get the actual cipher text bytes by removing the first 64 bytes from the cipherText string.
    const cipherTextBytes = cipherTextBytesWithSaltAndIv.slice(
      (this.keySize / 8) * 2,
    );

    const keyBytes = pbkdf2Sync(
      passPhrase,
      saltStringBytes,
      this.derivationIterations,
      this.keySize / 8,
      'sha1',
    );

    const decipher = createDecipheriv('aes-256-cbc', keyBytes, ivStringBytes);
    const plainTextBytes = Buffer.concat([
      decipher.update(cipherTextBytes),
      decipher.final(),
    ]);

    return plainTextBytes.toString('utf8');
  }

我尝试创建一种加密方法，因为我以为我会更好地理解这个问题，但我遇到了同样的错误

encrypt(plainText: string, passPhrase: string) {
    // Salt and IV is randomly generated each time, but is preprended to encrypted cipher text
    // so that the same Salt and IV values can be used when decrypting.
    const saltStringBytes = randomBytes(this.keySize / 8);
    const ivStringBytes = randomBytes(this.keySize / 8).toString('hex');
    const plainTextBytes = Buffer.from(plainText, 'utf8');

    const password = pbkdf2Sync(
      passPhrase,
      saltStringBytes,
      this.derivationIterations,
      this.keySize / 8,
      'sha1',
    );

    const cipher = createCipheriv('aes-256-cbc', password, ivStringBytes);

    const encrypted = Buffer.concat([
      saltStringBytes,
      Buffer.from(ivStringBytes, 'hex'),
      cipher.update(plainTextBytes),
      cipher.final(),
    ]);

    return encrypted.toString('base64');
  }

我实际上从 C# 代码“翻译”了这段代码，它使用 Rfc2898DeriveBytes 和 RijndaelManaged。

更新

我发现 C# 代码取自这个post

我错过了什么？
