Michiel Visser	caf533bddf	LibCrypto: Add ECDSA signature checking with secp256r1	2023-10-30 10:17:39 -06:00
Michiel Visser	e07ec02470	LibCrypto: Move all elliptic curve private methods into .cpp ... All the elliptic curve implementations had a long list of private methods which were all stored in a single .cpp file. Now we simply use static methods instead.	2022-03-20 00:51:50 +03:30
Michiel Visser	66d99c83d9	LibCrypto+LibTLS: Add SECP256r1 support to LibTLS ... Add the required methods to SECP256r1 to conform to the EllipticCurve virtual base class. Using this updated version of SECP256r1, support in LibTLS is implemented.	2022-03-20 00:51:50 +03:30
Michiel Visser	8f7219c6fa	LibCrypto: Implement the SECP256r1 elliptic curve ... 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.	2022-03-18 07:56:47 +03:30
