Package for removing Mach-O code signatures
npm install macho-unsignPackage for removing Mach-O code signatures
A broken code signature is often worse than no signature, so it can be desirable to remove a signature.
This package can remove code signatures from Mach-O binaries.
Both thin and fat binaries are supported.
Just pass an ArrayBuffer or an object that is a view of an ArrayBuffer to the unsign function.
If the binary is signed, an unsigned binary in a new ArrayBuffer will be returned.
If the binary has no signatures, null will be returned.
``js
import {readFile, writeFile} from 'node:fs/promises';
import {unsign} from 'macho-unsign';
const unsigned = unsign(await readFile('macho-binary'));
if (unsigned) {
console.log('Signature Removed', unsigned);
await writeFile('macho-binary-unsigned', Buffer.from(unsigned));
} else {
console.log('Not signed');
}
``
