Evercrypt & HACL Rust bindings

Maturity Level Build & Test ARM Build codecov Rust Version

High-level evercrypt bindings crates.

⚠️ Note: This crate is still work in progress. Don't use in production just yet.


By default the Evercrypt crate includes the random feature that allows generating random values (keys, nonces, etc.). But this is not verified code and uses the rand crate. It can be disabled with --no-default-features. Please bring your own randomness if you want to be safe.

RustCrypto AES

Evecrypt currently implements AES only for x64 CPUs with a certain set of CPU instructions. To provide AES for other platforms the Evercrypt crate uses the RustCrypto AES implementation when using --features rust-crypto-aes.


Currently only Linux x64 and MacOS are supported. Windows builds are on the To Do list and should be supported in future.

Platform Supported
MacOS Arm64
iOS Simulator x86_64
Linux x64
Linux x86
Windows x64
Arm64 Linux
Arm32 Linux


To run benchmarks use cargo bench.


All primitives are tested against the Wycheproof test vectors. They can be run with cargo test. This will also run automatically generated binding tests from bindgen.
