[jira] [Commented] (ZOOKEEPER-4415) Zookeeper 3.7.0 : The client supported protocol versions [TLSv1.3] are not accepted by server preferences
[ https://issues.apache.org/jira/browse/ZOOKEEPER-4415?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17499602#comment-17499602 ]
Anoop Negi commented on ZOOKEEPER-4415:
---------------------------------------
Hi [~tsaarni],
Thanks a lot for you response and the workarround
Yes TSLv1.3 is working well with ssl.ciphersuites.
Only doubt related to TLSv1.2 cipher suits as we are not sure on client and to support legacy clients (which might using be java8 and lower, and as java9 onwards GCM ciphers get preference) can we append GCM and CBS TLSv1.2 cipher, would that be ok?
or if all client should/must use java9 + then only GCM would be sufficient?
Regards,
Anoop
