RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Alexander Sosedkin 2021-06-21 09:28:32 UTC 
This bug was initially created as a copy of Bug #1882178

I am copying this bug because: while I'm not comfortable with neither bumping 1023 to 1024 and adding extra backend files in RHEL-8, let's at least do it in 9.


LEGACY crypto policy sets jdk.tls.ephemeralDHKeySize to 1023, which is invalid and would throw exception if it was actually used [1].

Also DH keySize < 1023 in jdk.tls.disabledAlgorithms property seems weird, if key size of 1023 does not make sense. (Is there reason for that?). Btw. RHEL-8 page about crypto says < 1024 are disabled [2].
