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.

I tried the above steps, and it works as expected.

Steps which I tried:

1. ECC CA: 
 1. Stoped CA.
 2. Modify the ciphers. Start CA.
 3. Able to reach the CA Agent and EE page.
 4. I could see that the specified algorithm in the server.xml is used for the communication. 
 For ECC I use: TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA384,
TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384

Wireshark Output:
```
# tshark -r /tmp/csqa_4_2.pcap -Y "ssl.handshake && frame.number==6" -T pdml | grep 'ssl.handshake.ciphersuite'
        <field name="ssl.handshake.ciphersuite" showname="Cipher Suite: TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384 (0xc02c)" size="2" pos="142" show="49196" value="c02c"/>
```

2. RSA CA:
 1. Stoped CA.
 2. Modify the ciphers. Start CA.
 3. Able to reach the CA Agent and EE page.
 4. I could see that the specified algorithm in the server.xml is used for the communication. 
 For RSA I use: TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384, TLS_RSA_WITH_AES_256_GCM_SHA384, TLS_DHE_RSA_WITH_AES_256_GCM_SHA384, TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384


Wireshark Output: 
```
# tshark -r /tmp/csqa_4_7.pcap -Y "ssl.handshake && frame.number==18" -T pdml | grep 'ssl.handshake.ciphersuite'
        <field name="ssl.handshake.ciphersuite" showname="Cipher Suite: TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 (0xc030)" size="2" pos="142" show="49200" value="c030"/>
