It appears that these were only ever used in bn_test.c...
libcrypto: make most of the BN_* macro pollution internal2025-12-05T14:12:32+00:00tb2025-12-05T14:12:32+00:00urn:sha1:f3f05f0cf8c30a990193e332e26fdd8e54b3f59b
This is a first sweep of reducing the number of terribly named macros
in bn.h More can go away. Those we need internally go to bn_local.h.
Annoyingly bn_internal.h uses some of them, so it includes bn_local.h
now. This can be cleaned up later.

Use 64 bit BN_ULONG on 64 bit Windows platforms.2025-11-07T13:41:40+00:00jsing2025-11-07T13:41:40+00:00urn:sha1:235bf5dad98ea543384128e2d21e8d4801b6c36c
64 bit Windows is a special LLP snowflake and it is currently incorrectly
using 32 bit BN_ULONG, since _LP64 is not defined. Enable 64 bit BN_ULONG
if _LP64 or _WIN64 is defined.

Use more specific types for BN.2025-11-05T13:00:26+00:00jsing2025-11-05T13:00:26+00:00urn:sha1:cfaf7540f6b19032df0f388ad6a4d0e0714671c6
Be specific about width and use uint64_t/uint32_t, rather than using
unsigned int/long/long long, based on platform. Additionally use UINT64_C()
and UINT32_C() for constants, along with PRI*64/PRI*32 for formatting. This
makes the platform responsible for providing the correct types/defines -
all we then need to do is determine is if BN should use a 32 bit or 64 bit
configuration.

Remove BN_DIV2W.2025-09-07T06:28:03+00:00jsing2025-09-07T06:28:03+00:00urn:sha1:98287b7cd5d64488bbaf57088225f91bd8e8a7f9
The BN_DIV2W define provides a code path for double word division via the C
compiler, which is only enabled on hppa. Simplify the code and mop this up.

Make BN_mod_exp2_mont() and BN_mod_exp_mont_word() internal2024-03-02T09:27:31+00:00tb2024-03-02T09:27:31+00:00urn:sha1:7542aebe05afee384f3e3d61ec0d1ea06fe2427c
The former could be useful but nothing uses it. The latter is a
dangerous implementation detail of Montgomery exponentiation that
should never have been leaked out of the library. Fix this.

This function is very slow and useful for testing purposes only. It
should never have been part of the public API. Remove it from there.
