Here is an example using BouncyCastle

    public static string ComputeSha1(string data)
    {
        var sha1Digest = new Org.BouncyCastle.Crypto.Digests.Sha1Digest();
        var hash = new byte[sha1Digest.GetDigestSize()];

        var dataBytes = Encoding.UTF8.GetBytes(data);
        foreach (var b in dataBytes)
        {
            sha1Digest.Update(b);
        }
        sha1Digest.DoFinal(hash, 0);

        return string.Join("", hash.Select(b => b.ToString("x2")).ToArray());
    }
