This crate implements AES-GCM 128 and 256, as well as AES-CCM 128 and 256.

It provides

• a portable, bit-sliced implementation
• an x64 optimised implementation using AES-NI
• an Aarch64 optimised implementation using the AES instructions

If you want to run tests on the riscv64gc-unknown-linux-gnu or armv7-unknown-linux-gnueabihf targets you can either follow the instructions provided in the rustc book (for RISC-V and for ARMv7), or use the pre-configured nix shell in this directory.

In both cases you will have to install the necessary target if you're working on a host different from the target:

rustup target add riscv64gc-unknown-linux-gnu
rustup target add armv7-unknown-linux-gnueabihf

If you have nix installed, you can now run

nix-shell --run "cargo test --target <target>"

to run tests on qemu-riscv64 or qemu-arm depending on choice of <target>.

Alternatively, you can install

• for RISC-V: the RISC-V GNU toolchain and qemu RISC-V emulator, or
• for ARMv7: the ARM GNU toolchain and qemu ARM emulator using the method of your choice.

Then you can run cargo test as follows:

cargo test --config config.toml --target <target>

where config.toml contains the linker and runner configuration (exact binaries/paths depending on your installation and may have to be adapted).
