# The Salsa20 core functions, in OCaml

An OCaml implementation of [Salsa20 Core](http://cr.yp.to/salsa20.html) functions, both Salsa20/20 Core and the reduced Salsa20/8 Core and Salsa20/12 Core functions.

The hot loop is implemented in C for efficiency reasons.

Salsa 20 Core are functions from 64-byte strings to 64-byte strings.

## Installation

```

opam install salsa20-core

```

## Usage

```ocaml

utop[0]> #require "salsa20-core";;

utop[1]> 0

|> Char.chr

|> String.make 64

|> Salsa20_core.salsa20_20_core (* or salsa20_12_core / salsa20_8_core *);;

- : string =

"\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000\000"
