TrustKit is an open-source Objective-C framework that simplifies deploying SSL public key pinning and reporting in iOS, macOS, tvOS, and watchOS apps. It supports both Swift and Objective-C, pins the certificate's Subject Public Key Info, and can report pinning validation failures to a server.

Use cases

• add ssl pinning to an ios app
• validate server certificates against pinned public keys on macos
• report ssl pinning validation failures to a backend
• enforce certificate pinning without modifying app source code
• configure an hpkp-style pinning policy in info.plist
• secure https connections in a tvos or watchos app

When to choose

• you need SSL public key pinning in an Apple-platform app with minimal code changes
• you want automatic pinning via NSURLConnection/NSURLSession delegate swizzling
• you need server-side reporting of pinning validation failures
• you support both Swift and Objective-C codebases

When to avoid

• you need SSL pinning on Android (use TrustKit-Android instead)
• your app targets iOS versions older than 12 or macOS older than 10.13
• you need pinning for non-Apple platforms or non-HTTP networking stacks
