错误：不支持状态或无法对数据进行身份验证

Question

我通过运行以下代码得到下面的错误。

错误：decipheriv.final（node：internal/crypto/cipher:196:29)在decrypt（/users/username/dev/playground/node/src/index.ts：14:65）处处于不支持状态或无法对数据进行身份验证

import crypto from "crypto";

const key = "13312156329479471107309870982123";

const encrypt = (message: string): string => {
  const iv = crypto.randomBytes(16);
  const cipher = crypto.createCipheriv("aes-256-gcm", key, iv);
  return `${cipher.update(message, "utf-8", "hex")}${cipher.final("hex")}`;
};

const decrypt = (message: string): string => {
  const iv = crypto.randomBytes(16);
  const decipher = crypto.createDecipheriv("aes-256-gcm", key, iv);
  return `${decipher.update(message, "hex", "utf-8")}${decipher.final(
    "utf-8"
  )}`;
};

console.log(decrypt(encrypt("hello")));

• 节点中aes-128-gcm的“不支持状态或无法验证数据”
• 在nodejs解密中获取错误（错误：不支持的状态或无法验证数据）

但我不认为我会因为同样的原因得到同样的错误。如有任何帮助，不胜感激。谢谢

IV对密码和破译都需要通用。应该读一下文件的

const key = crypto.randomBytes(32);
const iv = crypto.randomBytes(16);

const encrypt = (message: string): string => {
  const cipher = crypto.createCipheriv("aes-256-cbc", key, iv);
  return `${cipher.update(message, "utf-8", "hex")}${cipher.final("hex")}`;
};

const decrypt = (message: string): string => {
  const decipher = crypto.createDecipheriv("aes-256-cbc", key, iv);
  return `${decipher.update(message, "hex", "utf-8")}${decipher.final(
    "utf-8"
  )}`;
};
