ObfuscateMacro

Swift macros for string obfuscation to protect sensitive data from binary analysis.

Overview

ObfuscateMacro transforms your strings at compile-time into obfuscated data, with runtime decoding when accessed. Each macro execution uses a different random seed, ensuring that only obfuscated data exists in your binary.

Installation

In Xcode, add ObfuscateMacro as a Swift Package dependency to your project:

1. File → Add Package Dependencies
2. Enter: https://github.com/p-x9/ObfuscateMacro.git
3. Select version: 0.10.0 or higher

Usage

Import and use the macro:

import ObfuscateMacro

let text = #ObfuscatedString("hello")

Obfuscation Methods

Available methods:

• bit shift: Applies bit shifting operations
• bit XOR: Uses XOR operations
• base64: Base64 encoding with additional obfuscation
• AES: AES encryption
• random: Randomly selects from above methods

Specify Method

let string = #ObfuscatedString("Hello", method: .bitXOR)

Random Selection

// Use any method
let string = #ObfuscatedString("Hello", method: .randomAll)

// Choose from specific methods
let string = #ObfuscatedString("Hello", method: .random([.bitXOR, .AES]))

Enhanced Security

Apply multiple layers of obfuscation:

#ObfuscatedString(
    "hello",
    repetitions: 5
)

Best Practices

Use this macro for sensitive data like API keys, tokens, and internal URLs. While obfuscation adds protection, remember it's just one part of a complete security strategy.
