Comment 2 for bug 892896

The bug now applies with a 4096 byte limit. I just increased the default key size from 2048 to 4096. The RSA keys will only be used for the diffie-hellman or tmp-rsa key exchange so it is better that have have the security. But this also gives us some more flexibility in the protocol.

Also, it will temporarily increase the message length limits until we can move past RSA encryption.
