If sumbody wants to try his hands on encryption & decryption using MD5 algorithm, then below are the two functions :
using System.Text;
using System.Security.Cryptography;
public static string EncryptMd5(string sOriginal)
{
string sPassKey = "16";
byte[] sPassKeyArray;
byte[] sOriginalArray = UTF8Encoding.UTF8.GetBytes(sOriginal);
MD5CryptoServiceProvider MD5Hash = new MD5CryptoServiceProvider();
sPassKeyArray = MD5Hash.ComputeHash(UTF8Encoding.UTF8.GetBytes(sPassKey));
MD5Hash.Clear();
TripleDESCryptoServiceProvider tripleDesCsp = new TripleDESCryptoServiceProvider();
tripleDesCsp.Key = sPassKeyArray;
tripleDesCsp.Mode = CipherMode.ECB;
tripleDesCsp.Padding = PaddingMode.PKCS7;
ICryptoTransform cTransform = tripleDesCsp.CreateEncryptor();
byte[] resultArray = cTransform.TransformFinalBlock(sOriginalArray, 0, sOriginalArray.Length);
tripleDesCsp.Clear();
return Convert.ToBase64String(resultArray, 0, resultArray.Length);
}
public static string DecryptMd5(string sToOriginal)
{
string sPassKey = "16";
byte[] sPassKeyArray;
byte[] sOriginalArray = Convert.FromBase64String(sToOriginal);
MD5CryptoServiceProvider MD5Hash = new MD5CryptoServiceProvider();
sPassKeyArray = MD5Hash.ComputeHash(UTF8Encoding.UTF8.GetBytes(sPassKey));
MD5Hash.Clear();
TripleDESCryptoServiceProvider tripleDesCsp = new TripleDESCryptoServiceProvider();
tripleDesCsp.Key = sPassKeyArray;
tripleDesCsp.Mode = CipherMode.ECB;
tripleDesCsp.Padding = PaddingMode.PKCS7;
ICryptoTransform cTransform = tripleDesCsp.CreateDecryptor();
byte[] resultArray = cTransform.TransformFinalBlock(sOriginalArray, 0, sOriginalArray.Length);
tripleDesCsp.Clear();
return UTF8Encoding.UTF8.GetString(resultArray);
}
