I would like to use the c# code from this API here:
https://bitbucket.org/arrivets/krake...e-view-default

to request the POST data in a VB Net program I have. All I really need converted to VB NET is the code below:

Code:
 private JsonObject QueryPrivate(string a_sMethod, string props = null)
        {
            // generate a 64 bit nonce using a timestamp at tick resolution
            Int64 nonce = DateTime.Now.Ticks;
            props =  "nonce=" + nonce + props;


            string path = string.Format("/{0}/private/{1}", _version, a_sMethod);
            string address = _url + path;
            HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(address);
            webRequest.ContentType = "application/x-www-form-urlencoded";
            webRequest.Method = "POST";
            webRequest.Headers.Add("API-Key", _key);

            
            byte[] base64DecodedSecred = Convert.FromBase64String(_secret);

            var np = nonce + Convert.ToChar(0) + props;

            var pathBytes = Encoding.UTF8.GetBytes(path);
            var hash256Bytes = sha256_hash(np);
            var z = new byte[pathBytes.Count() + hash256Bytes.Count()];
            pathBytes.CopyTo(z, 0);
            hash256Bytes.CopyTo(z, pathBytes.Count());

            var signature = getHash(base64DecodedSecred, z);

            webRequest.Headers.Add("API-Sign", Convert.ToBase64String(signature));

            if (props != null)
            {

                using (var writer = new StreamWriter(webRequest.GetRequestStream()))
                {
                    writer.Write(props);
                }
            }

            //Make the request
            try
            {
                //Wait for RateGate
                _rateGate.WaitToProceed();

                using (WebResponse webResponse = webRequest.GetResponse())
                {
                    using (Stream str = webResponse.GetResponseStream())
                    {
                        using (StreamReader sr = new StreamReader(str))
                        {
                            return (JsonObject)JsonConvert.Import(sr);
                        }
                    }
                }
            }
            catch (WebException wex)
            {
                using (HttpWebResponse response = (HttpWebResponse)wex.Response)
                {
                    using (Stream str = response.GetResponseStream())
                    {
                        using (StreamReader sr = new StreamReader(str))
                        {
                            if (response.StatusCode != HttpStatusCode.InternalServerError)
                            {
                                throw;
                            }
                            return (JsonObject)JsonConvert.Import(sr);
                        }
                    }
                }

            }
        }
Now, I know I can throw this into a c# to vb net converter, but it doesn't work as well as I planned. I am having some issues with the SHA256 portion.
