+`libsodium-bindings` exposes a set of FFI bindings from the `libsodium` library, version 1.0.18 and above.
 It has no other dependency than `base`, and the documentation is strong enough to stand alone.

+See [LibSodium.Bindings](https://hackage-content.haskell.org/package/libsodium-bindings/candidate/docs/LibSodium-Bindings.html) for a list of available functions.
