The Everest team is pleased to announce the release of official OCaml 
bindings for all of our verified cryptographic algorithms, now available 
through OPAM as packages hacl-star and hacl-star-raw.

We provide bindings for the following:
- HACL*, a library of pure C algorithms
- Vale, a collection of optimized core assembly routines for maximum 
performance
- EverCrypt, an agile, multiplexing API with CPU auto-detection that 
brings together HACL* and Vale.

Our code is compiled from the F* programming language to C via the 
KReMLin compiler ("K&R meets ML"). We offer two OPAM packages:
- hacl-star-raw consists of low-level ocaml-ctypes bindings generated by 
KReMLin
- hacl-star is a hand-written OCaml idiomatic API that uses much more 
pleasant signatures, types and abstractions and is also safer, as it 
checks all static preconditions at run-time

We support AES{128,256}-GCM, Chacha20-Poly1305, Curve25519 / Ed25519, 
P256, MD5, SHA-{1,2,3} (all variants), Blake2 (s&b), HMAC/HKDF, and the 
HPKE and SecretBox high-level APIs. Some algorithms are optimized for 
Intel chips, notably AES-GCM -- see 
https://hacl-star.github.io/Supported.html for full details.

General documentation about the project is available at 
https://hacl-star.github.io/index.html -- sample code for the OCaml API 
is provided as part of the test suite 
https://github.com/project-everest/hacl-star/tree/master/bindings/ocaml/tests

This work was performed by Victor Dumitrescu from Nomadic Labs, one of 
the teams responsible for the core development of the Tezos blockchain.

Happy hacking,

Jonathan, on behalf of the Everest Team
