A repository I'm using to learn hashing with GLib.

POLYVAL per RFC 8452

A zero-dependency C++17 AES encryption library supporting AES-128, AES-192, and AES-256 in ECB, CBC, CTR, and GCM modes, with SIMD-accelerated backends and runtime CPU dispatch

Browser-based MAC demo — HMAC, CMAC, Poly1305, and GHASH compared with live length extension attack, timing attack, and nonce reuse demonstrations. Real WebCrypto operations. No backends. No simulated math.

Browser-based AES-GCM vs AES-GCM-SIV comparison — live nonce reuse attack showing keystream XOR recovery and GHASH key extraction, synthetic IV construction visualizer, and side-by-side misuse-resistance comparison. RFC 8452. Part of crypto-lab.
