AFNetworking pin public key for a trusted certificate

Question

I use AFNetworking 2.3.1, I have a trusted certificate for which I'd like to pin the public key.

I have the crt, key, pfx files, so I imagine I have to add them into my bundle.

AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc]
    initWithRequest:request];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation,
        id responseObject) {
    NSLog(@"Success");
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    return [self processError:[operation response]];
}];
[operation start];

Now how can I tell AFNetworking to use the AFSSLPinningModePublicKey mode ?
(I don't see the setSSLPinningMode method from AFHTTPRequestOperation)

And how do I tell AFNetworking to use the added key ? I can't find any example on the documentation.

Answer 1

AFNetworking has an AFSecurityPolicy object has values for security features, including the SSL pinning mode.

You can set the securityPolicy on an AFHTTPRequestOperation:

AFSecurityPolicy *securityPolicy = [AFSecurityPolicy policyWithPinningMode:AFSSLPinningModePublicKey];
operation.securityPolicy = securityPolicy;

Your certificate must have the extension cer not crt and should be in DER format. Add it to your bundle. You can convert it to the correct format in a terminal with the following command:

openssl x509 -in domain.crt -out domain.cer -outform der

You should not include keys in your app bundle, only the certificate is required.

Answer 2

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];

/**** SSL Pinning ****/
AFSecurityPolicy *securityPolicy = [[self alloc] init];
securityPolicy.SSLPinningMode = AFSSLPinningModePublicKey;
[manager setSecurityPolicy:securityPolicy];
/**** SSL Pinning ****/

[manager GET:WEBSITE_URL parameters:params
    success:^(AFHTTPRequestOperation *operation, NSDictionary* responseObject) {
    //..... beautiful code here
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    //..... beautiful code here
}];

Hope this help
