A nifty little extension method that generated the MD5/SHA-1 hash of a string. These methods are a continuation of my previous post:

public static string MD5(this string value)

{

    System.Security.Cryptography.MD5 algorithm =

        System.Security.Cryptography.MD5.Create();

    byte[] data = Encoding.ASCII.GetBytes(value);

    data = algorithm.ComputeHash(data);

    string md5 = "";

    for (int i = 0; i < data.Length; i++)

    {

        md5 += data[i].ToString("x2").ToLower();

    }

    return md5;

}

Just substitute MD5 for SHA1, SHA256, SHA384, SHA512 or RIPEMD160 which ever hash algorithm fits your needs.
