A toolkit for recovering files encrypted by LockBit 3.0 ("Black") ransomware without paying the ransom, by exploiting a known keystream-reuse weakness. Complete rewrite with multiprocessing, multi-oracle strategy, OpenMP brute-force, and cross-platform support (Linux/Windows).
Browser-based one-time pad demo — perfect-secrecy encrypt/decrypt, then the two-time-pad break: XOR two ciphertexts under a reused key and crib-drag to recover both plaintexts. Real XOR over real bytes. No backends. No simulated math.
Add a description, image, and links to the keystream-reuse topic page so that developers can more easily learn about it.
