Originally suggested solution for "Return Of the Hidden Number Problem" is arguably too expensive. While it has marginal impact on slower curves, none to ~6%, optimized implementations suffer real penalties. Most notably sign with P-256 went more than 2 times[!] slower. Instead, just implement constant-time BN_mod_add_quick. Reviewed-by:

Note that exported functions maintain original behaviour, so that external callers won't observe difference. While internally we can now perform Montogomery multiplication on fixed-length vectors, fixed at modulus size. The new functions, bn_to_mont_fixed_top and bn_mul_mont_fixed_top, are declared in bn_int.h, because one can use them even outside bn, e.g. in RSA, DSA, ECDSA... Reviewed-by:

The new flag marks vectors that were not treated with bn_correct_top, in other words such vectors are permitted to be zero padded. For now it's BN_DEBUG-only flag, as initial use case for zero-padded vectors would be controlled Montgomery multiplication/exponentiation, not general purpose. For general purpose use another type might be more appropriate. Advantage of this suggestion is that it's possible to back-port it... bn/bn_div.c: fix memory sanitizer problem. bn/bn_sqr.c: harmonize with BN_mul. Reviewed-by:

The old numbers where all generated for an 80 bit security level. But the number should depend on security level you want to reach. For bigger primes we want a higher security level and so need to do more tests. Reviewed-by:

This changes the security level from 100 to 128 bit. We only have 1 define, this sets it to the highest level supported for DSA, and needed for keys larger than 3072 bit. Reviewed-by:

"Computationally constant-time" means that it might still leak information about input's length, but only in cases when input is missing complete BN_ULONG limbs. But even then leak is possible only if attacker can observe memory access pattern with limb granularity. Reviewed-by:
