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, 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.

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

• Multithread:
  • openmp (optional)
  • pthread (optional)

• 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

This library is released under the AGPL-3.0 license.
