WHAT YOU WILL OPERATE
Follow a DES Feistel round, compare mathematical keyspace search times, see Triple DES compatibility, and step through AES-128’s real state transformations.
EDUCATIONAL BOUNDARY
This browser-only exhibit uses fixed public teaching vectors. It does not crack passwords, search visitor keys, transmit data, or store secrets.
IMPORTANT CONTEXT
DES is obsolete for modern protection. AES remains foundational, but a cipher alone is not a complete secure system: constructions, nonces, randomness, and key management matter.
