我正在尝试使用tripleDES算法进行解密。 编码部分如下：
try
{
System.Security.Cryptography.TripleDESCryptoServiceProvider des = new System.Security.Cryptography.TripleDESCryptoServiceProvider();
des.IV = new byte[8];
System.Security.Cryptography.PasswordDeriveBytes pdb = new System.Security.Cryptography.PasswordDeriveBytes(key, new byte[-1 + 1]);
des.Key = pdb.CryptDeriveKey("RC2", "MD5", 128, new byte[8]);
byte[] encryptedBytes = Convert.FromBase64String(file);
System.IO.MemoryStream ms = new System.IO.MemoryStream(file.Length);
System.Security.Cryptography.CryptoStream decStream = new System.Security.Cryptography.CryptoStream(ms, des.CreateDecryptor(), System.Security.Cryptography.CryptoStreamMode.Write);
decStream.Write(encryptedBytes, 0, encryptedBytes.Length);
decStream.FlushFinalBlock();
byte[] plainBytes = new byte[Convert.ToInt32(ms.Length - 1) + 1];
ms.Position = 0;
ms.Read(plainBytes, 0, Convert.ToInt32(ms.Length));
decStream.Close();
return Encoding.UTF8.GetString(plainBytes);
}
catch (Exception ex)
{
throw;
}
