Problems with SSL Pinning and AFNetworking 2.5.0 (NSURLErrorDomain error -1012.)

Question

We’ve been having a hard time securing our app’s network connections with SSL using AFNetworking 2.5.0.

We use a self-signed certificate authority and implemented a

Answer 1

- (AFSecurityPolicy *)securityPolicy {
    NSString *cerPath = [[NSBundle mainBundle] pathForResource:@"*.something.co.in" ofType:@"cer"];
    NSData *certData = [NSData dataWithContentsOfFile:cerPath];
    AFSecurityPolicy *securityPolicy = [AFSecurityPolicy policyWithPinningMode:AFSSLPinningModeCertificate];
    [securityPolicy setAllowInvalidCertificates:YES];
    [securityPolicy setPinnedCertificates:@[certData]];
    [securityPolicy setValidatesDomainName:NO];
    [securityPolicy setValidatesCertificateChain:NO];
    return securityPolicy;
}

This worked for me for some reason. Still not sure how this changes things because other connections in my app work without taking all these steps.

This is what the error generating security policy looks like -

- (AFSecurityPolicy *)securityPolicy {
    NSString *cerPath = [[NSBundle mainBundle] pathForResource:@"*.something.co.in" ofType:@"cer"];
    NSData *certData = [NSData dataWithContentsOfFile:cerPath];
    AFSecurityPolicy *securityPolicy = [AFSecurityPolicy policyWithPinningMode:AFSSLPinningModeCertificate];
    [securityPolicy setAllowInvalidCertificates:NO];
    [securityPolicy setPinnedCertificates:@[certData]];
    [securityPolicy setValidatesDomainName:YES];
    return securityPolicy;
}

Now sticking to the "Don't fix if it ain't broken" rule
