Ctf Crypto

When you hit a CTF binary that's doing something cryptographic, this walks you through the investigation: finding crypto strings and constants, identifying whether it's AES or some cursed custom cipher, tracing where keys come from, and spotting the implementation mistakes that make it solvable. It's focused on the binary reversing side of crypto challenges, not pure math problems. The framework covers pattern recognition for standard algorithms, data flow analysis to track key material, and the common CTF weaknesses like hardcoded keys or weak RNGs seeded with constants. The methodology is solid for systematically pulling apart crypto implementations rather than guessing, and it knows the difference between breaking real crypto versus exploiting sloppy challenge code.
