I believe the Half-Life network protocol uses Blowfish...

...however, the demos are playable even without a connection to WON (so no
public/private key exchange is happening).  Perhaps the key used to encrypt
the demo is stored as part of the demo when you begin recording it (since
you need that key to unencrypt it later to view it).
