reap-14-software-cracking-research SKILL.md skillA
reap-14-software-cracking-research from joasasantos/rea-prompts is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

REA prompt pack: Software cracking research (3 ready-to-paste prompts). Use when doing reverse-engineering investigation of software cracking research with REA (rea.tools) via an AI coding agent.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# REAP — 14. Software cracking research Part of REAP (REA Investigation Prompts). Replace everything in <angle brackets>; keep each request focused on one feature. Demand file/function/address evidence and separate facts from hypotheses. > For studying protection schemes, crackmes/CTFs, malware-adjacent RE, and > hardening your own software. Not a guide to pirate other people's products. ### Keygen-repair style analysis (document, don't bypass) ```text Use REA on <binary> to find the validation routine for <license key / serial>. Recover the algorithm (decompile it), identify the input encoding, the checksum/transform steps and the success/failure branches with addresses. Then write a test harness that exercises the recovered algorithm against sample inputs. Do not patch or bypass anything — I want the algorithm documented, not the check removed. ``` ### Crackme / CTF challenge solving ```text Use REA on this crackme: <path>. Enumerate entry points, strings, imports and any packer/protection indicators. Identify the flag-checking logic, decompile it, and derive the correct input from the recovered algorithm. Show the full evidence chain: address → instruction → conclusion. …

How to install
mdr add joasasantos/rea-prompts/reap-14-software-cracking-research@sha256:0324cb4f9e1c4719The line at the top of this page pins the label git:20261025.9bd45a8, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
