IU-8 BMSTU Feistel net

Experimental 128-bit block cipher with a 256-bit key and 14 rounds, exploring deterministic key-derived architectures, topology, nonlinear transformations, and reversible coupling. Researchers and independent analysts are explicitly encouraged to analyze and attempt to break the construction.

Browser-based DES demo — full 16-round Feistel with real S-boxes, PC-1/PC-2 key schedule and IP/FP, checked against archived NIST CAVP vectors. Complementation, 2DES meet-in-the-middle, and Sweet32: a 64-bit block colliding at the birthday bound to leak a repeated plaintext out of CBC.
