Zero the Hero (0tH) is a Mach-O structural analysis tool written in Rust.

It parses FAT binaries, load commands, slices, CodeSignature/SuperBlob, DER entitlements, requirements bytecode, and CodeDirectory versions.

The binary is universal (Intel + ARM64), notarized and stapled.

Motivation: existing tools lack full coverage of modern Mach-O signature internals.

Happy to discuss signature internals or Mach-O specifics.
