  1. You can see all the details at: https://github.com/mratsim/constantine , but to answer your "how" question briefly here, something Nim shares with most (all?) "systems programming languages" is "easy" integration with assembly languages --…

  3. Great question, first of all I did extensive research https://github.com/mratsim/constantine/wiki/Constant-time-ar... . Then the library defines its own types SecretBool and SecretWord throughough library that cannot be mixed with regular…
