I think the easiest way is to use the PCLCrypto nuget package. Then you can do:

private static string CalculateSha1Hash(string input)
{
        // step 1, calculate MD5 hash from input
        var hasher = WinRTCrypto.HashAlgorithmProvider.OpenAlgorithm(HashAlgorithm.Sha1);
        byte[] inputBytes = Encoding.UTF8.GetBytes(input);
        byte[] hash = hasher.HashData(inputBytes);

        StringBuilder sb = new StringBuilder();
        for (int i = 0; i < hash.Length; i++)
        {
            sb.Append(hash[i].ToString("X2"));
        }
        return sb.ToString();
}
