> They see me rollin', they hatin'.
Experiment on rolling my own crypto. Kinda. I'm not creating any new
protocol, but implementing known algorithms and constructions. The main
focus is to understand how to implement the math behind the algorithms,
and to get to know the constructions better.
Algorithms
==========
Utilities
---------
- Constant-time operations
- [x] compare
