Matthieu Pizenberg (Jun 05 2024 at 23:31): Matthieu Pizenberg (Jun 05 2024 at 23:31):I’m trying to implement the poly1305 hash function, which basically consists in computing few additions and multiplications over U256 numbers followed by a modulo (2^130 - 5), which is prime. Is anybody aware of an U256 impl already available somewhere?
Richard Feldman (Jun 05 2024 at 23:36):this looks like a Rust one: https://docs.rs/primitive-types/latest/primitive_types/struct.U256.html
Matthieu Pizenberg (Jun 05 2024 at 23:44):Seems it’s implemented with a macro that I can’t find construct_uint
Matthieu Pizenberg (Jun 05 2024 at 23:45):ah coming from the uint package
Matthieu Pizenberg (Jun 06 2024 at 08:04):oh my, it’s kinda involved. Do I want that much of a segway ... probably not ...
