I had some Encoding trouble with European Culture and Special Characters.
Here is a "Global" working version of @GrahamEHughes Code.
There are two Changes:

  1. Usage of Encoding.UTF8 instead of Encoding.Default in GetHash
private static string GetHash(string secret, string name, string email, string timems)
        {
            var input = name + secret + email + timems;
            var keybytes = Encoding.UTF8.GetBytes(secret);
            var inputBytes = Encoding.UTF8.GetBytes(input);
            var crypto = new HMACMD5(keybytes);
            var hash = crypto.ComputeHash(inputBytes);
            return hash.Select(b => b.ToString("x2"))
                .Aggregate(new StringBuilder(),
                    (current, next) => current.Append(next),
                    current => current.ToString());
        }
  1. Change of datetime Calculation:
    string timems = DateTimeOffset.UtcNow.ToUnixTimeSeconds().ToString();
