Raku Cryptography Playground

Audited & minimal JS implementation of hash functions, MACs and KDFs.

A FIPS 202 compliant SystemVerilog implementation of the Keccak permutation (SHA-3/SHAKE). Features a high-frequency multi-cycle architecture, runtime-configurable modes (SHA3-256/512, SHAKE128/256), and standard AXI4-Stream interfaces with full backpressure support. Verified using embedded SVA properties and official NIST test vectors.
