Hi. This patch updates libksba to 1.6.3 on the core-updates branch, which goes together with the security graft to 'master' that I posted here: https://lists.gnu.org/archive/html/guix-patches/2022-12/msg01053.html I have built it and tried to test it, but I'm not certain what a good way to test that a newly built package works as expected, so I'm looking for feedback. /Simon
