Crate sponge_hash_aes256 

SpongeHash-AES256

A sponge-based secure hash function that uses AES-256 as its internal PRF.

This hash function has a variable output size and can produce outputs of any non-zero size (up to usize::MAX).

Please see the SpongeHash256 struct for details! 💡

Dependencies

This crate is #![no_std] compatible and does not link the Rust standard library.

Required dependencies: aes, cipher, wide, zeroize

Optional features

Feature	Meaning
tracing	Dump the internal state to the logging sub-system (via log::trace()) after each step.

Rust support

This crate uses Rust edition 2021, and requires rustc version 1.89.0 or newer.
