Date: |
Sun, 17 Jun 2018 14:38:29 -0700 |
* lib/md4.c, lib/md5.c, lib/sha1.c, lib/sha256.c, lib/sha512.c:
* lib/sm3.c: Include <byteswap.h>.
(SWAP): Use its macros rather than reinventing the wheel.
* modules/crypto/md4, modules/crypto/md5-buffer:
* modules/crypto/sha1-buffer, modules/crypto/sha256-buffer:
* modules/crypto/sha512-buffer, modules/crypto/sm3:
(Depends-on): Add byteswap.
