Hi Bruno, I have 55efbb1178e045d52b0f52a2160f3d943c4f8a2c but the patch fails to apply. $ wget -qO- https://lists.gnu.org/archive/html/bug-gnulib/2018-05/txtdxlUGSMYnt.txt |patch -p1 patching file lib/md5.c Hunk #1 FAILED at 221. 1 out of 1 hunk FAILED -- saving rejects to file lib/md5.c.rej patching file lib/sha1.c Hunk #1 FAILED at 209. 1 out of 1 hunk FAILED -- saving rejects to file lib/sha1.c.rej patching file lib/sha256.c Hunk #1 FAILED at 273.

For SHA1 and other hashes, an ASM implementation of the algorythm with SSSE3 or AVX2 is compiled into the kernel.
