I've only had a brief look, but there are some (uint64_t*) to (uint32_t*) casts in src/multiply_32.c addmul128 which look like undefined behavior to me (strict aliasing rule). I notice BEBIT which looks like an attempt at big-endian support which clearly hasn't worked. A recent commit I noticed: https://github.com/Legrandin/pycryptodome/commit/aa5fac10a1c3a5f2b98c35954ae74207d545ec13 James
