Lightweight Asymmetric Encryption for C2 Implants — from XOR to Rabin KEM

Why Rabin beats RSA for implants: ~60 lines of pure C, no external deps, no heavy constants, provably as hard as factoring.

Covers the full crypto pipeline: XOR → AES-CTR → Rabin key encapsulation, with a working Python toolkit.
