PQS
Petoron Quantum Standard (PQS)
...PBKDF2-HMAC-SHA256 (200k iterations, adjustable) for password hardening.
Key separation via BLAKE2s - independent keys for encryption and MAC.
BLAKE2s-MAC authentication - 16-byte tag, any modification = instant rejection.
Streaming keystream generator - secure, large-scale XOR without key reuse.
Fake padding (HEAD/TAIL) - obfuscates binary boundaries and payload structure.
Precise size encoding - restores original payload exactly.
Supports files up to 128 MB per encrypted block.
No dependencies, fully offline, cross-platform Python implementation.
