iPhone: HTTPS client cert authentication

Question

I\'m fighting with a client certificate authentication. When a server needs a credential (a certificate in this case), this method is invoked from NSURLConnection d

Answer 1

I use these steps:

1. extract SecIdentityRef from the pkcs12 certificate file using SecPKCS12Import function
2. use SecIdentityCopyCertificate function to get SecCertificateRef

and the rest (a credential initialization) is the same as in my question... I can put here more code if you want. Note that there is a bug (http://openradar.appspot.com/7090030) in the iphone simulator, so it is not possible to work with a lot of certifcates in the simulator.

Answer 2

Of course the problem was with the iPhone simulator in xcode :) After updating to version 3.1 it started to work...

Answer 3

You can also search for identity in keychain if you store this information there:

+ (SecIdentityRef)dumpSecIdentityRef
{
OSStatus    err;
CFArrayRef  result;
CFIndex     resultCount;
CFIndex     resultIndex;

result = NULL;
err = SecItemCopyMatching((__bridge CFDictionaryRef) [NSDictionary dictionaryWithObjectsAndKeys:
                                                      (__bridge id)kSecClassIdentity,
                                                      kSecClass, kSecMatchLimitAll,
                                                      kSecMatchLimit, kCFBooleanTrue,
                                                      kSecReturnRef, kCFBooleanTrue,
                                                      kSecReturnAttributes, nil],
                          (CFTypeRef *) &result);

if ((result != NULL) && (err == noErr)) {

    NSMutableArray *identitiesArray = [NSMutableArray new];

    resultCount = CFArrayGetCount(result);
    for (resultIndex = 0; resultIndex < resultCount; resultIndex++) {
        NSDictionary *  thisResult;
        thisResult = (__bridge NSDictionary *) CFArrayGetValueAtIndex(result, resultIndex);
        NSLog(@"%@", (__bridge id)(result));
        [identitiesArray addObject:thisResult];
    }

    CFRelease(result);
    //TO DO - choose correct identity object from array.
    SecIdentityRef myIdentity = (__bridge SecIdentityRef)([[identitiesArray objectAtIndex:0] valueForKey:@"v_Ref"]);

    return myIdentity;
}
return nil;
}
