I've moved it from mpunsafe.c into the main mpint.c, and renamed it mp_mod_known_integer, because now it manages to avoid leaking information about the mp_int you give it. It can still potentially leak information about the small _modulus_ integer - hence the word 'known' in the new function name. This won't be a problem in any existing use of the function, because it's used during prime generation to check divisibility by all the small primes, and optionally also check for residue 1 mod the RSA public exponent. But all those values are well known and not secret. This removes one source of side-channel leakage from prime generation. |
