## Introduction

 Welcome to Virgil Pythia Library! 

**Virgil Pythia** is a C library which implements all required cryptographic functions and primitives to perform an implementation of [Pythia](http://pages.cs.wisc.edu/~ace/papers/pythia-full.pdf), the most **advanced protocol** of protecting passwords and generating keys based on passwords.

Pythia’s originators are: Adam Everspaugh and Rahul Chaterjee, University of

Wisconsin—Madison; Samuel Scott, University of London; Ari Juels and Thomas Ristenpart,

Cornell Tech.

## Library purposes

Pythia Library allows developers to implement Pythia service and client flows using the supplied functions.

## Dependencies

### Libraries

  - Multithread:

      - openmp (optional)

      - pthread (optional)

### Platform dependent features

  - when *TIMER* eqals *CYCLE* (optional)

      - intitialization occurs within function `arch_init()`

  - random number generator

      - `CryptGenRandom` on Windows

      - `/dev/random` on Unix/Linux

      - `/dev/urandom`  on Unix/Linux

      - `libc rand()/random()` is crossplatform (insecure!)

      - `zero seed` is a crossplatform (insecure!)

      - `custom` can be defined on a client side for any platform
