Introduction
Welcome to the documentation for grcodesignatureverifier – a library for verifying code signatures in iOS apps. This library is designed to help iOS developers ensure that their app’s code is signed and not tampered with, providing an extra layer of security.
Installation
- Step 1: Open your Xcode project
- Step 2: Add the grcodesignatureverifier library to your project
- Step 3: Import the library in your code files
- Step 4: Build and run your project to verify the installation
Usage
The grcodesignatureverifier library provides a simple API for verifying code signatures. Here’s how you can use it:
Verifying Code Signature
- Step 1: Import the grcodesignatureverifier library in your code file
- Step 2: Call the
verifyCodeSignature()
function, passing the app’s bundle identifier as a parameter - Step 3: Check the return value of the function –
true
indicates a valid code signature, whilefalse
indicates an invalid or tampered code signature - Step 4: Handle the verification result based on your application’s logic
Examples
Here are a few examples that demonstrate the usage of the grcodesignatureverifier library:
Example 1: Verifying Code Signature
// Import the grcodesignatureverifier library
import grcodesignatureverifier
// Verify the code signature
let isSignatureValid = verifyCodeSignature("com.yourapp.bundleidentifier")
if isSignatureValid {
print("Code signature is valid.")
} else {
print("Code signature is invalid or tampered.")
}
Example 2: Handling Invalid Signatures
// Import the grcodesignatureverifier library
import grcodesignatureverifier
// Verify the code signature
let isSignatureValid = verifyCodeSignature("com.yourapp.bundleidentifier")
if isSignatureValid {
// Proceed with your app's logic
} else {
// Display an error message or take appropriate action
showAlert("Invalid code signature detected.")
}
