Subject [jira] [Commented] (HDFS-6605) Client server negotiation of cipher suite
Date Wed, 02 Jul 2014 22:58:24 GMT

    [ https://issues.apache.org/jira/browse/HDFS-6605?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14050831#comment-14050831

Charles Lamb commented on HDFS-6605:
------------------------------------

bq. Charles, I'd rather not do getCipherSuites now, since there isn't a way for a client to
configure multiple CipherSuites right now. This JIRA is just so we can compatibly add more
suites later, but it's not something we're planning to support in the short term.

Understood.

+1 on the new diffs.

> For compatibility purposes, the client and server should negotiate what cipher suite
to use based on their respective capabilities. This is also a way for the server to reject
old clients that do not support encryption.
