With most ciphers (including the one that was chosen in the
displayed server-hello), wireshark can do the decryption when it
you supply the private key of the server (see the ssl protocol
preferences).
There is no support (yet?) for supplying the negotiated keys directly.
This means you *need* to be able to get hold of the private key and
the cipher used must not use Diffie-Hellman, because in that case
the negotiated keys cannot be determined by network traffic combined
with the private key.
I'm not sure if and how IE or Firefox can be directed to dump the
negotiated keys. If this is possible, support for supplying the
negotiated keys might be a nice improvement to (wire|t)shark indeed :-)
