显示错误填充无效，无法删除.

问题描述

嗨 iam在基于Windows的application.im中尝试尝试解密加密密码.我可以很好地加密密码，但是我尝试显示这样的decrpt错误

填充无效，无法删除

我使用下面的代码

Hi iam working in windows based application.im trying to decrpt an encrypt password .i can encrypt passwords well but im trying decrpt error showing like this

Padding is invalid and cannot be removed

Iam using below code

string Salt = "Kosher", HashAlgorithm = "SHA1";

            int PasswordIterations = 2;
            string InitialVector = "OFRna73m*aze01xY";

            int KeySize = 256;
            if (string.IsNullOrEmpty(CipherText))
                return "";
            byte[] InitialVectorBytes = System.Text.Encoding.ASCII.GetBytes(InitialVector);
            byte[] SaltValueBytes = System.Text.Encoding.ASCII.GetBytes(Salt);

            byte[] CipherTextBytes = Convert.FromBase64String(CipherText);
            PasswordDeriveBytes DerivedPassword = new PasswordDeriveBytes(Password, SaltValueBytes, HashAlgorithm, PasswordIterations);
            byte[] KeyBytes = DerivedPassword.GetBytes(KeySize / 8);
            RijndaelManaged SymmetricKey = new RijndaelManaged();
            SymmetricKey.Mode = CipherMode.CBC;
            byte[] PlainTextBytes = new byte[CipherTextBytes.Length];
            int ByteCount = 0;
            using (ICryptoTransform Decryptor = SymmetricKey.CreateDecryptor(KeyBytes, InitialVectorBytes))
            {
                using (MemoryStream MemStream = new MemoryStream(CipherTextBytes))
                {
                    using (CryptoStream CryptoStream = new CryptoStream(MemStream, Decryptor, CryptoStreamMode.Read))
                    {

                        ByteCount = CryptoStream.Read(PlainTextBytes, 0, PlainTextBytes.Length);
                        MemStream.Close();
                        CryptoStream.Close();
                    }
                }
            }
            SymmetricKey.Clear();
            return System.Text.Encoding.UTF8.GetString(PlainTextBytes, 0, ByteCount);

error happening in

 ByteCount = CryptoStream.Read(PlainTextBytes, 0, PlainTextBytes.Length) this line as  <br />
<br />
<br />
Padding is invalid and cannot be removed<br />
<br />
<br />
Any body know why error like this arising?<br />
<br />
Thanks in Advance
