ios validate self signed certificate

Quote:

I did figure out how to resolve this issue. I ended up comparing the client and server trust certificates, byte-by-byte. Although there could be another way to resolve such issues of self-signed certificate, but for this solution did work. Here is how I'm doing comparison of the client and server certificates, byte-by-byte, using their CFData objects(you can also reference 'AdvancedURLConnections' example code provided by Apple): success = NO; pServerCert = SecTrustGetLeafCertificate(trust); if (clientCert != NULL) { CFDataRef clientCertData; CFDataRef serverCertData; clientCertData = SecCertificateCopyData(clientCert); serverCertData = SecCertificateCopyData(pServerCert); assert(clientCertData != NULL); assert(serverCertData != NULL); success = CFEqual(clientCertData, serverCertData); CFRelease(clientCertData); CFRelease(serverCertData); } if (success) { [[challenge sender] useCredential:credential forAuthenticationChallenge:challenge]; [self printLogToConsole:@"Success! Trust validation successful."]; } else { [self printLogToConsole:@"Failed! Trust evaluation failed for service root certificate.\n"]; [[challenge sender] cancelAuthenticationChallenge:challenge]; } Hope this will help someone, who is looking for solution of similar issue,
