Re: [S390x] Optimize SHA1 with fat build support

Applying hardware-accelerated SHA3 instruction to optimize sha3_permute function for s390x arch has an insignificant impact on the performance, I'm wondering what we can do to take full advantage of those instructions. Optimizing sha3_absorb seems a good way to go since the s390x-specific

I added support for the sha1_compress_n function on arm architecture in the same branch https://git.lysator.liu.se/mamonet/nettle/-/tree/sha1-compress-n regards, Mamone On Sat, Aug 21, 2021 at 5:22 AM Maamoun TK wrote: > On Thu, Aug 19, 2021 at 8:48 AM Niels Möller wrote: > >> Maamoun TK

What is x86/sha1-compress.nlms? How can I implement nettle_copmress_n function for that particular type? regards, Mamone On Sun, Aug 15, 2021 at 2:10 AM Maamoun TK wrote: > On Thu, Aug 12, 2021 at 4:26 PM Maamoun TK > wrote: > >> On Tue, Aug 10, 2021 at 11:55 PM Niels Möller >> wrote: >> >>>

[S390x] Optimize SHA1 with fat build support

I made a merge request in the main repository that optimizes SHA1 for s390x architecture with fat build support !33 . regards, Mamone ___ nettle-bugs mailing list
