How to Perform SSL Pinning in iOS Apps

Secure Sockets Layer (SSL) is the standard security protocol used to establish an encrypted link between a web server and a browser. This link ensures that all data passed between the web server and browser remain private and secure. SSL is an essential security measure for any website or application that handles sensitive user data.

In order to set up SSL, website owners must obtain an SSL certificate from a Certificate Authority (CA). Once they have done so, they can install the certificate on their web server and enable SSL. When SSL is enabled, visitors to the website will see a padlock icon in their browser’s address bar, indicating that the site is secure.

One additional security measure that can be taken is known as SSL pinning. With SSL pinning, a specific Certificate Authority’s certificate is hard-coded into an app. This ensures that even if someone were to obtain a valid SSL certificate from a different CA, the app would still refuse to connect to it. In this way, SSL pinning adds an extra layer of protection against man-in-the-middle attacks.

What is SSL Pinning?

SSL Pinning is the process of ensuring that the SSL certificate used by a given website or app is the same one that was originally supplied by the server. This helps to prevent man-in-the-middle attacks, where a malicious actor intercepts communications between a user and a server in order to steal data or inject malware.

While SSL Pinning can be a useful security measure, it can also cause problems for users if not implemented properly. For example, if a user tries to access a website or app that has SSL Pinning enabled but does not have the correct SSL certificate, they will be unable to connect. This can lead to frustration and may even deter some users from using the site or app altogether.

It is important to weigh the risks and benefits of implementing SSL Pinning before deciding whether or not to use it in your iOS app. If you do choose to use SSL Pinning, be sure to test it thoroughly to ensure that it does not cause any problems for your users.

The Need for SSL Pinning

As our lives move increasingly online, security becomes more and more important. When we browse the web, we expect our data to be safe from prying eyes, and our communications to be private. To achieve this, we rely on encryption – ensuring that only the intended recipient can read our messages.

One type of encryption commonly used is SSL/TLS, which is the protocol that powers HTTPS – the secure version of HTTP. When you visit a website over HTTPS, your browser verifies that the site’s SSL certificate is valid, and then uses that certificate to establish an encrypted connection. Once the connection is established, all traffic between your browser and the website is encrypted, making it much harder for anyone to eavesdrop on or tamper with your data.

However,SSL/TLS is not perfect. There have been a number of high-profile security breaches in recent years that have exploited vulnerabilities in SSL/TLS implementations. As a result, it’s important to take steps to further secure your data, even when using HTTPS. One way to do this is by using SSL pinning.

How to Implement SSL Pinning in iOS Apps

SSL pinning is a security measure that helps to ensure that the data being transmitted between an app and a server is encrypted and not susceptible to being intercepted by a third party. In order to implement SSL pinning, developers need to configure their apps to verify the identity of the server before establishing a connection. This can be done by either checking for the presence of specific certificates or public keys. Once SSL pinning has been configured, any attempt by a third party to intercept the data being transmitted will likely result in the app being unable to establish a connection with the server.

Pros and Cons of SSL Pinning

When it comes to securing data transmitted between an iOS app and its backend server, SSL pinning is a popular choice. SSL pinning helps to ensure that the data is not being intercepted by a third-party, and also that the server is who it claims to be.

However, SSL pinning is not without its drawbacks. One of the biggest disadvantages is that it can make debugging difficult, since you need to have the correct SSL certificate installed on your device in order for the connection to work. Another downside is that if the certificate ever changes (for example, if the server’s certificate expires), then your app will no longer be able to connect.

Overall, SSL pinning can be a helpful security measure, but it’s important to weigh the pros and cons before deciding if it’s right for your app. You can always hire dedicated developers for the SSL pinning.


By following the steps laid out in this article, you can successfully add SSL pinning to your iOS app. This will help to ensure that all communications between your app and your server are secure, and it will also help to prevent man-in-the-middle attacks.
