My initial investigation points to this being a problem with Ruby support for OpenSSL 3. On RHEL 9, OpenSSL 3 is available and Ruby does not have full support for it. The support it does have appears to be good enough for RHEL 9 in non-FIPS mode but once the additional restrictions of FIPS are in place the support breaks. This means there is presently no work-around available.

We will either need to wait for the fix in Ruby and to propagate through the RHEL release cycle or to consider a re-write of the foreman_scap_client into a different language (e.g. python).

Is there a RHEL bugzilla open to track the issue that Eric has found in comment 1?
If not, can one be created?

Thanks!

ssh-rsa algorithm is disabled in RHEL 9.  So the system reverts to Ed25519 algorithm to try to scp the report to the Satellite server but this algorithm is not allowed in FIPS mode.  I dont know why it wont use ecdsa algorithm since it is enable in the sshd_config file.

This bug is blocked by a RHEL bug that has to be fixed in Ruby itself, and is being tracked by https://issues.redhat.com/browse/RHEL-5590

This seems to be resolved in latest ruby shipped with rhel 9.4.
