# Common crypto docs

## Introduction

The `commoncrypto` library is responsible for providing all cryptographic functions necessary to `keygen`, `initfsgen` and later VyBuild

## Detailled informations

Folder: `Blastproof/commoncrypto`

It's build using VyBuild, as both a static and shared library. The provided build file doesn't allow yet for the library to be build outside of Vystem build process.

The `-Ofast -march=native` is used on every source file, to make it faster in every use case.

The library include the following external cryptographic library:
