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.

Additionally, you can control the curves with the system-wide cryptographic policies through the `Groups` configuration option. The following Brainpool curves are enabled in OpenSSL ECC: * `brainpoolP256r1` * `brainpoolP256t1` * `brainpoolP320r1` * `brainpoolP320t1` * `brainpoolP384r1` * `brainpoolP384t1` * `brainpoolP512r1` * `brainpoolP512t1`	Story Points:	---

Description Sahana Prasad 2023-04-20 02:29:44 UTC

Description of problem:
Currently brainpool curves in ECC are disabled.

After discussing with RH-legal, we are now permitted to allow Brainpool curves.
There is a request to enable Brainpool curves by customers like Samsung (attached customer case).

Changes as part of this bug, will therefore enable long brainpool curves in ECC by default. Short curves are still disabled as they are unsafe to be used.

Actual results:
Brainpool curves are disabled.

Expected results:
Brainpool curves (long) are enabled in ECC by default.

Setting a doc type, but we still need to fill the doc text.
