libbb: code shrink

2026-01-28T08:03:02+00:00

Fix some compiler warnings and move the CNG algorithm caches into get_alg_handle(). Saves 32 bytes in the x86_64 build with CNG enabled.

libbb: refactor CNG hashing implementation

2026-01-27T12:45:11+00:00

The existing CNG implementation relied on multiple features only implemented in "newer" Windows versions. This new implementation does not use the aforementioned features and is therefore compatible with systems running Windows Vista or higher. function old new delta .rdata 87112 87288 +176 hmac_peek_hash 80 208 +128 get_alg_handle - 96 +96 algorithm_provider_hmac_cache - 48 +48 algorithm_provider_cache - 48 +48 alg_id_mappings - 48 +48 sha512_begin 16 48 +32 sha384_begin 16 48 +32 sha256_begin 16 48 +32 sha1_begin 16 48 +32 md5_begin 16 32 +16 hmac_hash_v 48 64 +16 hmac_end 48 64 +16 hmac_blocks.constprop.0 96 112 +16 __imp_BCryptOpenAlgorithmProvider - 8 +8 __imp_BCryptDuplicateHash - 8 +8 BCryptOpenAlgorithmProvider - 8 +8 BCryptDuplicateHash - 8 +8 ------------------------------------------------------------------------------ (add/remove: 8/0 grow/shrink: 10/0 up/down: 768/0) Total: 768 bytes

win32: deduplicate die_if_error()

2025-07-11T10:47:56+00:00

There were two copies of the static function die_if_error(). Replace these with a single external function. Saves 16 bytes.

Use Windows library for cryptographic checksums

2025-06-09T12:23:49+00:00

Add a new feature to libbb, FEATURE_USE_CNG_API, which enables the use of the Cryptography API: Next Generation library to calculate checksums. It is disabled by default except in the mingw64u default config, as the API requires Windows 10+ to function. Usage of this API provides a size benefit and delegates hardware optimizations to the operating system cryptography library. Based on GitHub PR #498 by rfl890. Saves 4064 bytes in the mingw64u case.

libbb: fix sha1 on !x86 if CONFIG_SHA1_HWACCEL=y

tls: fix CONFIG_FEATURE_TLS_SHA1=y + CONFIG_SHA1_HWACCEL=y

2024-07-12T17:30:14+00:00

The check for result hash size was buggy for CONFIG_SHA1_HWACCEL=y. While at it, document CPUID use a bit better. function old new delta get_shaNI - 28 +28 sha1_end 66 79 +13 sha256_begin 83 60 -23 sha1_begin 111 88 -23 ------------------------------------------------------------------------------ (add/remove: 1/0 grow/shrink: 1/2 up/down: 41/-46) Total: -5 bytes Signed-off-by: Denys Vlasenko
