### NOTE on AES
To speed up AES, there are a few options available:
- `RUSTFLAGS="--cfg aes_armv8" cargo build --release` ensures that the ARMv8 AES instructions are used if available.
By default, the `aes` feature auto-detects the best AES implementation for your platform
for x86 and x86_64,
but not on ARMv8 where it defaults to the software implementation as of this writing.
To enable the ARMv8 AES instructions, the `aes_armv8` feature is enabled in the `.cargo/config` file in this crate.
Enabling aesni provides the fastest Aes algorithm.
### NOTE on SHAKE
Shake auto detects the best implementation for your platform.
