How to Perform SSL Pinning in iOS Apps

Last Updated on August 18, 2022 by Rashid Hassan

Apple’s security features are always in demand, which is why they’ve been working on SSL pinning for a while now. In this article, we’ll be walking you through how to set up SSL pinning in your iOS apps, so that users can be sure that their data is being protected when they interact with your app.

What is SSL Pinning?

SSL pinning is a security feature that allows an app to protect itself by requiring all traffic to be sent over a secured connection. SSL pinning is enabled by default on devices running iOS 11 and later, and can be disabled on older devices.

When you enable SSL pinning in your app, all requests from the user’s device are sent over a secure connection. This ensures that all data transmitted between your app and the user’s device is protected against eavesdropping and data theft.

If you want to use SSL pinning in your app but don’t have access to a Secure Sockets Layer (SSL) server, you can use Apple’s built-in SSL certificate provider. To do this, you need to create a self-signed certificate using Keychain Access and then add it to your app’s Info.plist file. Once your certificate is added, your app will be able to use it to secure connections with users’ devices.

Disable SSL Pinning in iOS Apps

If you are an iOS app developer and want to disable SSL pinning, then this guide will show you how. SSL pinning is a security measure that links an app’s certificate to its install location on a device. This way, if the app is maliciously installed on a device, the malicious app cannot access secure data. 

In order to disable SSL pinning for your app, first you need to know your app’s certificate file name. Your certificate file name can be found in the “Certificates” section of your Xcode project settings under “General”. Once you know your certificate file name, you can disable SSL pinning by editing the AppDelegate’s application:didFinishLaunchingWithOptions: method like so:

– (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { // Override point for customization after application launch NSLog(@”SSL Pinning Disabled”); return YES; }

Now your app can access secure data without being disabled by SSL pinning!
