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:

It was false positive, but one can as well view it as readability issue. Switch even to unsigned indices because % BN_BYTES takes 4-6 instructions with signed dividend vs. 1 (one) with unsigned. Reviewed-by:

To avoid the possibility that someone creates rem.exe, rem.bat or rem.cmd, simply don't use it. In the cases it was used, it was to avoid empty lines, but it turns out that nmake handles those fine, so no harm done. Reviewed-by:

It seems that nmake first tries to run executables on its own, and only pass commands to cmd if that fails. That means it's possible to have nmake run something like 'echo.exe' when the builtin 'echo' command was expected, which might give us unexpected results. To get around this, we create our own echoing script and call it explicitly from the nmake makefile. Fixes #6670 Reviewed-by:
