AEGIS for Rust

This is a Rust implementation of the AEGIS authenticated cipher, ported from the Zig standard library.

AEGIS is extremely fast on CPUs with AES acceleration, has a large nonce size, and is key committing.

Cargo flags

std: allow dynamic allocations

std is the default.

IMPORTANT: In order to get decent code on x86 and x86_64 CPUs, you should set additional rustc flags prior to compiling that crate or a project using it:

export RUSTFLAGS="-Ctarget-feature=+aes,+sse4.1"

A benchmark can be run that way:

export RUSTFLAGS="-C target-cpu=native -Ctarget-feature=+aes,+pclmul,+sse4.1"
cargo bench

Benchmarks

Benchmarks take a 16384 bytes input block. Results are in bytes per second.
