Subject: fips no-des: compile out TDES KAT
X-Git-Tag: openssl-3.5.0-alpha1~968
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9d70bba1353fa897ef0cc1b48cc00f55b155f803;p=thirdparty%2Fopenssl.git

fips no-des: compile out TDES KAT

FIPS provider correctly supports no-des build time option and doesn't
advertise DES related algorithms. However KAT test for DES is still
attempted to be executed and fails.

This prevents configuring FIPS provider without legacy behaviour as
defined in SP 800-131Arev2. Also see #25761 internal docs.

Fix `enable-fips no-des` build option, and add a daily checker for
"legacy-free" (as much as currently feasible) FIPS configuration.
