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.

- Constant-time operations
|
|
|
|
|
- [/] compare: returns `0` if match, non-`0` otherwise. The non-`0`
|
|
|
|
|
case might leak information. Would be better to return `0xffffffff`
|
|
|
|
|
if match, `0` otherwise.
