Crypto Keccak / SHA3

Implementation of crypto code with MicroPython

The SHA-3 (Secure Hash Algorithm 3) and SHAKE functions are cryptographic hashing algorithms that are part of the SHA-3 family, standardized by the National Institute of Standards and Technology (NIST).

The library implements the following fixed size hash fonctions: SHA3-224, SHA3-256, SHA3-384, SHA3-512 and SHAKE128, SHAKE256 the for variable size hashes.

The code was developed and tested on RP2350. It is compatible with RP2040 / ESP32
