More specifically, I am getting the error 0x00002F8F from WinHttpSendRequest, which is ERROR_INTERNET_DECODING_FAILED (which indicates to me that its a cert error). I have imported the cert on this machine, and http://stackoverflow.com/questions/19338395/how-do-you-use-winhttp-to-do-ssl-with-a-self-signed-cert am able to pull up the page in IE without a cert error.

TLDR: How do you use WinHTTP with a self signed cert? c++ c winapi ssl winhttp share|improve this question asked Oct 12 '13 at 19:38 cylus 61112 add a comment| 1 Answer 1 active oldest votes up vote 4 down vote accepted For WinHTTP, in order to accept/allow SSL validation failures, you must first make the request and allow it to fail, then disable the security checks and retry the operation on the request handle. Something along the lines of: // Certain circumstances dictate that we may need to loop on WinHttpSendRequest // hence the do/while do { retry = false; result = NO_ERROR; // no retry on success, possible retry on failure if(WinHttpSendRequest( mHRequest, WINHTTP_NO_ADDITIONAL_HEADERS, 0, optionalData, optionalLength, totalLength, NULL ) == FALSE) { result = GetLastError(); // (1) If you want to allow SSL certificate errors and continue // with the connection, you must allow and initial failure and then // reset the security flags. From: "HOWTO: Handle Invalid Certificate // Authority Error with WinInet" // http://support.microsoft.com/default.aspx?scid=kb;EN-US;182888 if(result == ERROR_WINHTTP_SECURE_FAILURE) { DWORD dwFlags = SECURITY_FLAG_IGNORE_UNKNOWN_CA | SECURITY_FLAG_IGNORE_CERT_WRONG_USAGE | SECURITY_FLAG_IGNORE_CERT_CN_INVALID | SECURITY_FLAG_IGNORE_CERT_DATE_INVALID; if(WinHttpSetOption( mHRequest, WINHTTP_OPTION_SECURITY_FLAGS, &d
