◦To enable MD5 for password encryption
conf/cassandra-env.sh
JVM_OPTS="$JVM_OPTS -Dpasswd.mode=MD5"

I saw this post on other forums and was wondering what this meant? I can't find it in any docs stating if this means it will find the password file and encrypt the password at rest or what will this encrypt with this option?

Also, while people are at it. . I need to enter credentials into OpsCenter in order to use Cassandra once we lock it down and putting the username and password in the config file in clear text kind of defeats the purpose. Any solutions yet?

That passwd.mode option only applies to SimpleAuthenticator, the example implementation of an authenticator that's provided with Cassandra.

With regards to OpsCenter, your best option would be to restrict the read permissions on the config file for that cluster (found under /etc/opscenterd/clusters/ if you installed a package, or conf/clusters/ otherwise).
