As far as I am concerned, Ethereal is one of the nicest gifts to the open source community. It is a fully blown network protocol analyzer which can be extended to accomodate virtually any protocol you can come up with.
One of the things that have been bugging me however, was that Ethereal was – for the longest time – not able to interpret SSL and TLS protected traffic in a meaningful way (yes, you could see the SSL traffic, but it was encrypted and therefore useless).
There has been a plugin/patch for Ethereal now available for some time, and it seems that it is finally in a useful state. Paolo Abeni has been working on this and the code can be obtained here: http://sourceforge.net/projects/ssl-decrypt
