The Low-Level Cryptography & Binary Security Lab

This is my main laboratory for Reverse Engineering.

Repository Structure

1. CrackMes

Solutions, analysis scripts, and detailed write-ups for "crackme" challenges from crackmes.one.

• 1 - 2 Difficulty:

  • Fundamental reverse engineering concepts.
  • Techniques include basic static analysis (Ghidra), dynamic analysis (GDB, ltrace), memory inspection, and handling ASLR/PIE protections.

• 2 - 3 Difficulty:

  • Focuses on intermediate reverse engineering tasks.
  • Techniques involve "Keygening" (writing custom key generators), algorithm reversing, and unpacking binaries.

Tools & Environment

The analyses are made by using these tools:

• Disassemblers/Decompilers: Ghidra
• Debuggers: GDB (GNU Debugger)
• Binary Analysis: strings, ltrace, strace, readelf, binwalk
• Scripting: Python
