Has anyone produced software (preferably Unix based) that provides a public key authenticated, DES/3DES encrypted datastream over WAN firewalls/bastions? A typical use would be to connect transaction feeds between two data centers in a secure, automated way over Internet. I can't see anything conceptually difficult with it, and it seems the PGP library could be used to create simple Unix daemons. sdw -- Stephen D.
