[ANN][EXCHANGE] Poloniex - Crypto Exchange with BTC/NXT

[singula]

Probably brute force protection, since not every account has 2FA enabled. I can understand it, but I agree it is really annoying.

But it shows even for 2FA enabled accounts. Change that stupidity to require recaptcha OR 2FA at step 2.

But before logging in there is no way to know whether the account you are about to login with has 2FA enabled right? 

Quite good compromise between usability and anti-bruteforce protection is to allow few (like 1 or 2) bad attempts per account or per IP address without captcha.
That way most people won't see the captcha all year long, as they usually enter the correct password and still it will make any bruteforcing difficult (even with large botnets and lots of IP's, bruteforcers will run out of these "free" attempts rather quickly)...

That's why captcha is supposed to be done at step 2. Captcha OR 2FA.

Hello,

i'm trying to use trading API with C#, but i got always "Invalid Key/Secret pair" error, the code is:

Code:

        private String getTradingRequestResponse(Dictionary<string, string> postData) {

            String url = "https://poloniex.com/tradingApi";
            SimpleHttp http = new SimpleHttp(url);

            postData.Add("nonce", this.nonce.ToString());
            String reqStr = SimpleHttp.BuildPostData(postData);
            String sign = BitConverter.ToString(this.hashMaker.ComputeHash(Encoding.ASCII.GetBytes(reqStr))).Replace("-","").ToLower();

            for (int i = 0; i < postData.Count; ++i) {
               KeyValuePair<string, string> onePost =  postData.ElementAt(i);
               http.AddPostParameter(onePost.Key, onePost.Value);
            }

            http.AddHeader("KEY", KEY);
            http.AddHeader("SIGN", sign);

            String pageResponse = http.ReadPage();
            return pageResponse;
        }

and " SimpleHttp.BuildPostData" function :

Code:

        public static String BuildPostData( Dictionary<String, String> postData){

            StringBuilder postDataString = new StringBuilder();

            foreach (KeyValuePair<String, String> elem in postData)
            {
                postDataString.Append(elem.Key + "=" + elem.Value + "&");
            }
            postDataString.Remove(postDataString.Length - 1, 1);
            return postDataString.ToString();
        
        }

please help me, i'm trying this for whole day and cant resolve ... the Key and Secret value are good, i checked many times

SimpleHttp http = new SimpleHttp(url);

Not simple, https://

[mimini0147]

SimpleHttp http = new SimpleHttp(url);

Not simple, https://

well, SimpleHttp is my class, i called that, but url is https:// as you can see "
            String url = "https://poloniex.com/tradingApi";"

inside this class i use WebRequest for http

[freddyfarnsworth]

HttpsServer
This class is an extension of HttpServer which provides support for HTTPS.

[freddyfarnsworth]

Back to poloniex I made new wallet addresses and transferred some coins today, all went well and speedy.

IE10 W7 64bit captcha and all working, now all ya gotta do is cloudflare

HttpsServer
This class is an extension of HttpServer which provides support for HTTPS.

but i can use WebRequest for public API, so why not work with Trading API...

Possible issue with BTC withdrawals, confirmed my btc being withdrawn from my poloniex account to my personal wallet and under past withdrawals it shows the transaction as COMPLETE:ERROR. My BTC was transferred to an unknown account when looking at the block chain. Waiting on poloniex support :/

Also having problem with BTC withdrawals. Email confirmations not coming for withdraws. Been waiting for literally hours and "resent" email 20x. Do not use this exchange! they are following the same bad patterns as cryptorush. Something is fishy here.

Please remove the Captcha, it's annoying as hell and I have problems reading it.

If you need it, show only after a failed login attempt.

Thanks.

I hate captchas and I think most people do. It would be better without them.
