# 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
