This repository contains my implementation of the ROCA attack.

It's a Sage implementation that uses multiprocessing.

For more information you can read my blog post about it.

The sage_functions.py file contains coppersmith's algorithm. I have to place it in a separate file so that I can import it in each subprocess.
