[jira] [Commented] (KNOX-566) Knox Jetty server is vulnerable to Logjam vulnerability

["Larry McCay (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/KNOX-566?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14619175#comment-14619175 ] 

Larry McCay commented on KNOX-566:
----------------------------------

I don't know that we can address this without switching to openssl for cert generation.
This happens to be a change that we are already considering in order to prepare for java 9 restrictions to accessing the needed classes.

The Knox generated certificates should only be used for out of the box/demo use and not for production.
Provisioning properly trusted certificates within a deployment should be done for production deployments.

[~jeffreyr_97@yahoo.com] - do you know of any IBM jdk ability to create appropriately sized keys? The last I saw the oracle/open jdk are both rather crippled there. Perhaps there has been some progress there but I haven't seen it.

> [root@bdvs1392 logs]# openssl s_client -connect bdvs1392.svl.ibm.com:8443 -cipher "EDH" | grep "Server Temp Key"
> depth=0 C = US, ST = Test, L = Test, O = Hadoop, OU = Test, CN = bdvs1392.svl.ibm.com
> verify error:num=18:self signed certificate
> verify return:1
