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
• aes_crate: use the aes crate, which works on all platforms
• aesni: use an optimized implementation for x86 CPUs with AES extensions

std, aes_crate is the default.
