Unity C# 加密错误

在对您的代码进行一些测试后，我最终使用了这两种方法。我认为您的代码的主要问题是Decrypt从未对plainTextBytes-array做任何事情。private static string Encrypt(byte[] plainTextBytes){    byte[] keyBytes = new Rfc2898DeriveBytes(PasswordHash, Encoding.ASCII.GetBytes(SaltKey)).GetBytes(256 / 8);    var symmetricKey = new RijndaelManaged() { Mode = CipherMode.CBC, Padding = PaddingMode.Zeros };    var encryptor = symmetricKey.CreateEncryptor(keyBytes, Encoding.ASCII.GetBytes(VIKey));    byte[] cipherTextBytes;    using (var memoryStream = new MemoryStream())    {        using (var cryptoStream = new CryptoStream(memoryStream, encryptor, CryptoStreamMode.Write))        {            cryptoStream.Write(plainTextBytes, 0, plainTextBytes.Length);            cryptoStream.FlushFinalBlock();            cipherTextBytes = memoryStream.ToArray();        }    }    return Convert.ToBase64String(cipherTextBytes);}解密public static byte[] Decrypt(string base64){    byte[] cipherTextBytes = Convert.FromBase64String(base64);    byte[] keyBytes = new Rfc2898DeriveBytes(PasswordHash, Encoding.ASCII.GetBytes(SaltKey)).GetBytes(256 / 8);    var symmetricKey = new RijndaelManaged() { Mode = CipherMode.CBC, Padding = PaddingMode.None };    var decryptor = symmetricKey.CreateDecryptor(keyBytes, Encoding.ASCII.GetBytes(VIKey));    using (var memoryStream = new MemoryStream(cipherTextBytes))    {        using (var cryptoStream = new CryptoStream(memoryStream, decryptor, CryptoStreamMode.Read))        {            using (BinaryReader srDecrypt = new BinaryReader(cryptoStream))            {                return srDecrypt.ReadBytes(cipherTextBytes.Length);            }        }    }}
