Pieter Wuille	08d54964e5	Improve bounds checks in modinv modules ... This commit adds functions to verify and compare numbers in signed{30,62} notation, and uses that to do more extensive bounds checking on various variables in the modinv code.	2021-03-11 10:25:22 -08:00
Pieter Wuille	d8a92fcc4c	Add extensive comments on the safegcd algorithm and implementation ... This adds a long comment explaining the algorithm and implementation choices by building it up step by step in Python. Comments in the code are also reworked/added, with references to the long explanation.	2021-03-08 09:56:07 -08:00
