This implementation of the secp256r1 elliptic curve uses two techniques to improve the performance of the operations. 1. All coordinates are stored in Jacobian form, (X/Z^2, Y/Z^3, Z), which removes the need for division operations during point addition or doubling. The points are converted at the start of the computation, and converted back at the end. 2. All values are transformed to Montgomery form, to allow for faster modular multiplication using the Montgomery modular multiplication method. This means that all coordinates have to be converted into this form, and back out of this form before returning them. |

SerenityOS
Graphical Unix-like operating system for x86 computers.
About
SerenityOS is a love letter to '90s user interfaces with a custom Unix-like core. It flatters with sincerity by stealing beautiful ideas from various other systems.
Roughly speaking, the goal is a marriage between the aesthetic of late-1990s productivity software and the power-user accessibility of late-2000s *nix. This is a system by us, for us, based on the things we like.
You can watch videos of the system being developed on YouTube:
