Hi,
Attended a presentation by Milkyway, vendor of the BlackHole firewall, which also does VPN. Supposedly the symmetric cipher used in the VPN is called CAST. Anyone has any info on it? TIA. Cheers.
It's a canadian cipher. It's inventors have the initials C.A. and S.T. pure coincidence they say. it's got a little write-up in Appl. Crypto 2, and I'll post anything I can about it as soon as I get home. I don't have my copy of ac2 on me... I do remember that it's patented, and you have to talk to these folks for licences I believe.... more to come later.
