The main purpose of the SHA checksums are to allow the daemon auth code
to pick a stonger digest method when negotiating the auth digest to use.
However, the SHA digests are also available for use in file checksums,
should someon really want to use one of them.
The new digests are listed from strongest to weakest at the start of the
daemon auth list, giving them the highest priority.
The new digests are listed from weakest to strongest near the end of the
checksum list, giving them the lowest priority of use for file
checksums.
- Size flist checksum data to hold the active size, not the max.
- Add a negotiated hash method to the daemon auth code.
- Use EVP for all openssl digests. This makes it easy to add more
openssl digest methods and avoids deprecation warnings.
- Support a way to re-enable deprecated digests via openssl conf
file and allow a default file to be configured.
- Supply a simple openssl-rsync.cnf file to enable legacy digests.
- Make the SIMD ASM code off by default. Use configure --enable-simd-asm
to enable.
- Allow MD5 ASM code to be requested even when OpenSSL is handling MD4
checksums. Use configure --enable-md5-asm to enable.
- Switch .s -> .S to enable the preprocessor.
- Move some defines from mdigest.h to md-defines.h.
- Tweak the asm file to use md-defines.h.
- Add a couple missing .h dependencies in the Makefile.
