WebAnother interesting finding from the output above is that the server permits DH key exchanges using a 1024-bit group. While a 1024-bit group is sufficient in many environments, attackers with nation-state size resources may be able to break the key exchange.

Currently with apache/mod_ssl, if DHE is enabled then a 1024-bit ephemeral key will be used. I found the following quote in Adam Langley's blog: Ideally the DH group would match or exceed the RSA key size but 1024-bit DHE is arguably better than straight 2048-bit RSA so you can get away with that if you want to.
