Hello colleagues,
I have been working on support for two particularly strange GOST curves, which are defined in Weierstrass form, but there exists a birationally equivalent Untwisted Edwards form (so all sign/verify calculations should be done in Edwards form). Major issues came from the fact that I have tried defining generator point in Edwards form (which is more logical).
During this rework I thought about switching ecc_point from bearing just x and y coordinates to have per-curve defined coordinates (like projectile or inverted).
WDYT?
