PHASH is a self-contained, dependency-free, post-quantum XOF hashing algorithm implemented in modern C++20.
This release delivers the first fully stable production implementation of the PetoronHash-System — a 1600-bit sponge-based hash function with domain separation, extendable output, and deterministic behavior.
Key Features
No external dependencies — pure C++20 implementation.
Extendable Output (XOF) — supports arbitrary output length (256–8192+ bits).
Post-quantum oriented design — ARX-based sponge resistant to Grover-type attacks.
Context and salt separation — unique hashing domains for each use-case.
Optimized performance — ~120–130 MB/s
Comprehensive verification — verify_all.sh performs KAT tests, determinism checks, and performance validation.
Verification Script:
chmod +x verify_all.sh
./verify_all.sh
