C#与javascript通用AES加密解密

山外青山更高一筹

nodejs-javascript版
  public static aesEncrypt(input: string, key: string): string {
    var iv = key;
    var cipher = crypto.createCipheriv('aes-128-cbc', key, iv);
    var crypted = cipher.update(input, 'utf8', 'binary');
    crypted += cipher.final('binary');
    crypted = Buffer.from(crypted, 'binary').toString('base64');

    return crypted;
  }

  public static aesDecrypt(input: string, key: string): string {
    var iv = key;
    var decode = Buffer.from(input, "base64").toString("binary")
    var cipher = crypto.createDecipheriv('aes-128-cbc', key, iv);
    var decrypted = cipher.update(decode, 'binary', 'utf8');
    decrypted += cipher.final('utf8');

    return decrypted;
  }
