NSS/ARGON2

Team

Introduction

We are a team of four Junior Undergraduates at National Institute of Technology, Trichy, majoring in Computer Science and Engineering. We have a wide range of overlapping and unique interests and we mostly tinker with stuff till it breaks. Works 70% of the time, all the time.

Project

Description

Argon2 is a memory hard function for password hashing and other applications. Argon2 is based on Blake2 and winner of the password hashing competition. The goal of this project is to provide basic Blake2 support for NSS and base Argon2 on it.

Resources

• Public Workpad : https://public.etherpad-mozilla.org/p/mwos-hashing
• Blake2 meta bug: https://bugzilla.mozilla.org/show_bug.cgi?id=1310763
• Argon2 meta bug: https://bugzilla.mozilla.org/show_bug.cgi?id=1310762

Scope

At present, it is limited to implementing the Blake2 functions as well as the password hashing function Argon2 on top of it.

Goals

• Blake2 implementation working on all platforms
• Argon2 implementation working on all platforms
• Functional tests
• Performance tests
• Good documentation
• Performance comparison with other implementations
