I really would like to see a "web of trust" like is used
for pgp, but for PKI keys that are used to automatically
negotiate encryption and/or authentication.

This would include IPSEC, SSL and hopefully the domain
keys mentioned above.

Having such a web of trust, we can:
- avoid the high cost of SSL certs from a commercial root
- do other nice things, like ipsec between dynamic IP
  addresses

Of course, we will need to come up with a way to securely
store the addresses and make sure the right user is still
using it.  This probably isn't as hard as it seems ...

If there is a web of trust, the user can have his personal
key (signed by others) on a floppy or usb keyfob and protected
with a password.  That personal key can be used to sign a key
that is not password protected, used for automatic negotiation
of encryption and valid for a limited time (say, a month).

That way the web of trust isn't broken when a breakin happens.

kind regards,

Rik
