Bittrex auth issue

[aph5nt]

Hi, I often get this type of error for private API operations. To solve this I have to generate a new set of auth tokens. But for some reason, after some time I get this error once again... I suspect it has something to Bittrex security policy.

Is it possible to get a more descriptive error message?

How to reproduce:

• get new Bittrex auth keys
• make API call (like getting orders)
• change IP address
• make API call (like getting orders)

System.Security.Cryptography.CryptographicException: Error occurred during a cryptographic operation.

I have never had this issue, so I am not sure, but you could try getting debugging info by setting BittrexClientOptions.LogVerbosity to Debug. Also, you could try to get the error info in the response message sent by Bittrex. If you have already tried this, then I don't know.

The code would look something like this:

private async void TestGetClosedWithdrawls()
{
    string key = "yourkey";
    string secret = "yourSecret";

    BittrexClientV3.SetDefaultOptions(new BittrexClientOptions
    {
        LogWriters = new List<TextWriter>() { Console.Out },
        LogVerbosity = LogVerbosity.Debug,
        ApiCredentials = new ApiCredentials(key, secret)
    });

    using (var client = new BittrexClientV3())
    {
        try
        {
            var result = await client.GetClosedWithdrawalsAsync();
            if (result.Success)
            {
                // do something with the data
            }
            else
            {   // print error info
                Console.WriteLine($"Failed to receive withdrawl records.");
                Console.WriteLine($"ResponseStatusCode = {result.ResponseStatusCode}");
                Console.WriteLine($"Error code = {result.Error.Code}");
                Console.WriteLine($"Error message = {result.Error.Message}");
                Console.WriteLine($"Error data = {result.Error.Data}");
            }
        }
        catch(Exception exception)
        {
            Console.WriteLine($"Caught an exception in TestGetClosedWithdrawls:");
            Console.WriteLine($"{exception}");
        }
    }
}
