String Encryption Algorithm

Hi 


I want a string to encrypt and save it to the database. I got the code below.

 

public static string Encrypt(string strToEncrypt, string strKey)

{

    try

    {

        TripleDESCryptoServiceProvider objDESCrypto =

                          new TripleDESCryptoServiceProvider();

        MD5CryptoServiceProvider objHashMD5 = new MD5CryptoServiceProvider();

        byte[] byteHash, byteBuff;

        string strTempKey = strKey;

        byteHash = objHashMD5.ComputeHash(ASCIIEncoding.ASCII.GetBytes(strTempKey));

        objHashMD5 = null;

        objDESCrypto.Key = byteHash;

        objDESCrypto.Mode = CipherMode.ECB;

        byteBuff = ASCIIEncoding.ASCII.GetBytes(strToEncrypt);

        return Convert.ToBase64String(objDESCrypto.CreateEncryptor().

                          TransformFinalBlock(byteBuff, 0, byteBuff.Length));

    }

    catch (Exception ex)

    {

        return "Wrong Input. " + ex.Message;

    }

}

 

I would like to know which algorithm is used in the code above. Please anyone give me the answer...

The code uses MD5 togenerate the output. MD5 is a one-way hashing algorithm which means that it's not possible to reverse the algorithm to get the original value back. Hashing is not encryption. So TripleDES is used to retrieve it back.
