In c# it can be very easy to generate a md5sum or an shasum. This can be done by using the CryptoServiceProvider which is in the System.Security.Cryptography name space.

The following function will generate a md5sum for a string of text

static string Md5Sum(string Input)
{
    MD5CryptoServiceProvider Crpyt = new MD5CryptoServiceProvider();

    byte[] buf = ASCIIEncoding.ASCII.GetBytes(Input);
    return BitConverter.ToString(Crpyt.ComputeHash(buf)).Replace("-", "").ToLower();
}

Or it can be changed to produce a sha checksum for a string of text in the following way.

static string ShaSum(string Input)
{
    SHA512CryptoServiceProvider Crpyt = new SHA512CryptoServiceProvider();

    byte[] buf = ASCIIEncoding.ASCII.GetBytes(Input);
    return BitConverter.ToString(Crpyt.ComputeHash(buf)).Replace("-", "").ToLower();
}
