Crate arwen_codesign 

Ad-hoc code signing for Mach-O binaries

This module implements ad-hoc code signing for Mach-O binaries, matching Apple’s codesign behavior for linker-signed binaries.

Example

use arwen_codesign::{adhoc_sign, AdhocSignOptions, Entitlements};

// Simple signing with just an identifier
let signed = adhoc_sign(data, &AdhocSignOptions::new("com.example.myapp"))?;

// With hardened runtime and preserved entitlements
let options = AdhocSignOptions::new("com.example.myapp")
    .with_hardened_runtime()
    .with_entitlements(Entitlements::Preserve);
let signed = adhoc_sign(data, &options)?;
