Browser-based national hash standard demo — SM3 (China), Streebog (Russia), and Kupyna (Ukraine) alongside SHA-256 and SHA-3. Five-way simultaneous hashing, avalanche analysis, and cryptographic sovereignty context.
Browser-based Ascon demo — NIST Lightweight Cryptography Standard (FIPS SP 800-232, 2025). Ascon-AEAD128 encrypt/decrypt with constant-time tag verification, Ascon-Hash256 with avalanche analysis, side-by-side comparison against AES-GCM and ChaCha20-Poly1305. Designed for IoT and embedded constraints. No backends. No external crypto libraries.
Browser-based AEGIS-256 authenticated encryption demo (draft-irtf-cfrg-aegis-aead-18). AES round function, 6-state sponge update, and tag derivation implemented from scratch and verified against official test vectors.
