Gates `asm` support under a crate feature. Uses the `cpufeatures` crate to detect the presence of the `sha3` extension for ARMv8 CPUs, automatically falling back to a software implementation if it isn't available. When the `asm` feature is enabled on `aarch64` targets, exposes `f1600_asm` that relies on ARMv8 `sha3` hardware intrinsics.
RustCrypto: Keccak Sponge Function
Pure Rust implementation of the Keccak Sponge Function including the keccak-f and keccak-p variants.
About
This crate implements the core Keccak sponge function, upon which many other cryptographic functions are built.
For the SHA-3 family including the SHAKE XOFs, see the sha3 crate, which
is built on this crate.
