Hi I have given the code here Decryption.cs
using System;
using System.Security.Cryptography;
using System.IO;
namespace SFTPCrypt
{
/// <summary>
/// Summary description for Decryption.

public class Decryption

}
private static byte[] Decrypt(byte[] cipherData, byte[] Key, byte[] IV)
{
// Create a MemoryStream that is going to accept the decrypted bytes
MemoryStream ms = new MemoryStream();
Rijndael alg = Rijndael.Create();
alg.Key = Key;
alg.IV = IV;
CryptoStream cs = new CryptoStream(ms, alg.CreateDecryptor(),
CryptoStreamMode.Write);
// Write the data and make it do the decryption
cs.Write(cipherData, 0, cipherData.Length);
cs.Close();
byte[] decryptedData = ms.ToArray();
return decryptedData;
}
// Decrypt a string into a string using a password
// Uses Decrypt(byte[], byte[], byte[])
public static string Decrypt(string cipherText, string Password)
{
byte[] cipherBytes = Convert.FromBase64String(cipherText);

new byte[] {0x49, 0x76, 0x61, 0x6e, 0x20, 0x4d, 0x65, 0x64, 0x76, 0x65, 0x64,
0x65, 0x76});
byte[] decryptedData = Decrypt(cipherBytes, pdb.GetBytes(32),
pdb.GetBytes(16));

I hope this will be usefull for u.
Otheriwse give me a call 9845908676
