Cryptographic strength: a fingerprint and a cipher

engineering

SHA-256 of the three letters 'abc' is a fixed 256-bit fingerprint — change one bit and it changes utterly (the property this engine's seals rest on) — and a 256-bit AES key is, by the standard, strong. Worked & sealed by the engine — SHA-256('abc') = ba7816bf…20015ad · AES-256 → strong. [HOLDS; open the seal to re-check.]
