Аутентификация сертификата клиента Swift iOS

технически, когда кто-то, кого я знаю, нуждался в реализации в Swift, он использовал следующую реализацию Objective-C, чтобы получить объект NSURLCredential для соединения; на основе закрытого ключа и пары сертификатов X509, содержащихся в хранилище ключей PKCS12.

Извините, у меня нет доступа к источнику с решением Swift. Все, что я знаю, это то, что NSURLCredential был возвращен Swift и использовался непосредственно в http-url-соединении. Это похоже но вот этому.

Я не разработчик iOS, поэтому я не смогу помочь вам с частью "мост к Swift".

EDIT:Хар хар, очень смешно, понижая меня дважды, когда вы сами не беспокоились, пока щедрость была. * grumble*

в любом случае, чтобы использовать следующее выше, вам просто нужно получить доступ к нему из Swift.

func connection(connection: NSURLConnection, willSendRequestForAuthenticationChallenge challenge: NSURLAuthenticationChallenge) {
    if let p12Data = UserManager.currentP12,
       let credential = CertificateManager.getCredentialsForP12(p12Data) as? NSURLCredential {
            challenge.sender.useCredential(credential, forAuthenticationChallenge: challenge)
    } else {
        UIApplication.sharedApplication().networkActivityIndicatorVisible = false
    }   
}

это использует это.

+ (id)getCredentialsForP12:(NSData *)p12 {
    NSData* p12data = p12;
    const void *keys[] = {kSecImportExportPassphrase};
    const void *values[] = {CFSTR("thePassword")};
    CFDictionaryRef optionsDictionary = CFDictionaryCreate(NULL, keys, values, 1, NULL, NULL);
    CFArrayRef p12Items;
    OSStatus result = SecPKCS12Import((__bridge CFDataRef) p12data, optionsDictionary, &p12Items);
    if (result == noErr) {
        CFDictionaryRef identityDict = CFArrayGetValueAtIndex(p12Items, 0);
        SecIdentityRef identityApp = (SecIdentityRef) CFDictionaryGetValue(identityDict, kSecImportItemIdentity);
        SecCertificateRef certRef;
        SecIdentityCopyCertificate(identityApp, &certRef);
        SecCertificateRef certArray[1] = {certRef};
        CFArrayRef myCerts = CFArrayCreate(NULL, (void *) certArray, 1, NULL);
        CFRelease(certRef);

        NSURLCredential *credential = [NSURLCredential credentialWithIdentity:identityApp certificates:nil persistence:NSURLCredentialPersistenceNone];
        CFRelease(myCerts);
        return credential;

    }
    else {
        // Certificate is invalid or password is invalid given the certificate
        NSLog(@"Invalid certificate or password");

        UIAlertView* av = [[UIAlertView alloc] initWithTitle:@"Error" message:@"Invalid cert or pass" delegate:nil cancelButtonTitle:@"ok" otherButtonTitles: nil];
        [av show];
        NSError *error = [NSError errorWithDomain:NSOSStatusErrorDomain code:result userInfo:nil];
        return nil;
    }

EDIT: быстрая версия выше здесь, хотя это было грязно достаточно того, что мы просто не использовать его.
