        Perform a hash and base64-encode:

// SHA1 hash:
string h1 = Convert.ToBase64String(new System.Security.Cryptography.SHA1CryptoServiceProvider().ComputeHash(Encoding.ASCII.GetBytes("one two")));

// MD5 hash:
string h2 = Convert.ToBase64String(new System.Security.Cryptography.MD5CryptoServiceProvider().ComputeHash(Encoding.ASCII.GetBytes("one two")))
