Question about encryption strength (DES versus AES256)

Quick question about encryption strength today …

from our internal wildfire server:

  • Connection established using EDH-RSA-DES-CBC3-SHA (TLSv1/SSLv3)

from jabber.org:

  • Connection established using AES256-SHA (TLSv1/SSLv3)

How can we achieve this higher level of encryption when communicating with wildfire? If I put my own certificate in the store that was created with a higher bit count, would that do it? or if the cert’’ I created (& however I had it processed by caCert or our internal CA) using certain switches to get it to use AES?

Thanks.

Cheers.

Peace.
