There is a bug in Core Update 183 regarding the openssl commands for creating a new root/host x509 certificate set.
This was due to an OpenSSL bug fix that was implemented in version 3.2.0
There have already been a couple of posts on this topic in the forum.
Please see the bug report
https://bugzilla.ipfire.org/show_bug.cgi?id=13595
for more details.
A patch to fix this has been submitted and will hopefully get into Core Update 184.
