Hi velu,
I faced the same problem, and worked out the sol too. I used
TripleDESCryptoServiceProvider with MD5 Hashing algo. The password was stored in db as
binary. Try the code below.

using System.Security.Cryptography;
public static byte[] EncryptPassword(string vstrPwd)
{
DefaultEncryptionKey = "secretpassword1";
hashmd5 = new MD5CryptoServiceProvider();
//hashmd5 = null;
des = new TripleDESCryptoServiceProvider();
des.Key = hashmd5.ComputeHash(ASCIIEncoding.ASCII.GetBytes(DefaultEncryptionKey));
des.Mode = CipherMode.ECB;
ICryptoTransform desdencrypt = des.CreateEncryptor();
ASCIIEncoding MyASCIIEncoding = new ASCIIEncoding();
byte[] buff = ASCIIEncoding.ASCII.GetBytes(vstrPwd);
//CipheredValue = Convert.ToBase64String(desdencrypt.TransformFinalBlock(buff, 0,
buff.Length));
byte[] CipheredValue = desdencrypt.TransformFinalBlock(buff, 0, buff.Length);
return CipheredValue;
}
public static string DecryptPassword(string vbytPwd)
{
DefaultEncryptionKey = "secretpassword1";
hashmd5 = new MD5CryptoServiceProvider();
//hashmd5 = null;
des = new TripleDESCryptoServiceProvider();
string DeCipheredValue = null;
des.Key = hashmd5.ComputeHash(ASCIIEncoding.ASCII.GetBytes(DefaultEncryptionKey));
des.Mode = CipherMode.ECB;
ICryptoTransform desdencrypt = des.CreateDecryptor();
byte[] buff = Convert.FromBase64String(vbytPwd);
//byte[] buff =vbytPwd;
DeCipheredValue = ASCIIEncoding.ASCII.GetString(desdencrypt.TransformFinalBlock(buff,
0, buff.Length));
return DeCipheredValue;
}
