# Binary Comparison

Compare security posture of two binaries: $0 and $1.

## Steps
1. Run checksec on both binaries:
   - `skwaq checksec $0`
   - `skwaq checksec $1`
2. Compare hardening differences
3. Ingest both and compare function counts, imports, strings
4. Identify functions present in one but not the other (patch analysis)
5. Report security improvements and regressions
