Will Price announced on mac-crypto (mailing list) that PGP 6.5
will include “PGPnet”, a complete IPSEC implementation for Windows
and Macintosh platforms, with the usual freeware versions to
follow. This, as well as tools like FreeS/WAN, allow secure and
authenticated communications between Internet hosts without
planning or preconfiguration. It sits at the IP layer, and thus is
able to encrypt and authenticate *all* TCP/IP traffic regardless of
application. This is a Very Good Thing. The more people run these
things, the better.
