Do not look into FreeBSD code ) You can take mine code: https://github.com/rozhuk-im/liblcb/blob/master/include/crypto/hash/sha2.h there is Plain C and SHA versions. I see SSE version in internet but do not implement it in mine sha2 code, only for sha1 now. ___ freebsd-current@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
Re: sha256 speed
There is support for the SHA intrinsic in aesni(4) that would be relatively easy to adapt to userspace for libmd, if someone was interested. Especially now that we demand linker ifunc support (on x86 platforms, at least). I posted a patch and some performance comparison in https://svnweb.freebsd.org/base?view=revision=r324037 .

sha256 speed
Hello, On my Ryzen the sha256 command is much slower than openssl dgst -sha256. For large files, openssl is more than 7 times faster in practice. You can also test it with the builtin benchmarks: sha256 -t openssl speed sha256 I think the reason is that openssl supports the SHA CPU extensions whereas libmd (used by sha256) does not. Any chance we can make the base sha256 faster?
