cryptography-libhydrogen-bindings

What is this?

A set of low-level bindings (and helpers) wrapping libhydrogen, commit 7bd39c471d31e654b132153c04e20ff49f257cb2.

What're the goals of this project?

Ease of use

No user of this library should ever have to think about C, linking to system libraries, enabling SIMD through weird flags, or any similar issues. Just add this as a dependency and go.

Minimality

No weird lawless type class hierarchy. No dependencies outside of base. These are truly minimal bindings, for those who want the ability to operate as close to the original code as posssible.

Stability and clarity

Just by reading the documentation of this library, you should know everything you need to use it. No reading the C 'documentation' should ever be required. Furthermore, you shouldn't need to doubt that this behaves - our CI should prove it to you. No surprises on upgrades either - impeccable PVP compliance only here.

How do I use this?

See the Haddocks for each of the public modules for explanations of what functions all do. These are deliberately kept close to C, as they're designed to be 'wrapped up' in whatever API you choose to expose.

What does this run on?

Our CI currently checks Windows, Linux (on Ubuntu) and macOS. We check the following GHC versions:

• 8.10.7
• 9.0.2
• 9.2.2

What can I do with this?

The bindings themselves are licensed under BSD-3-Clause, while the C code for libhydrogen is under ISC. See the LICENSE and LICENSE.LIBHYDROGEN files for more information.
