As I am fond of saying these days: the key fingerprint is the identity. The TLS public key infrastructure (PKI) exists to map an alphanumeric string (domain) to a particular key fingerprint. So for critical stuff involving, say, executable cryptographic code, it would be good if there was a way to specify the fingerprint as well as the domain to the browser in the provided link. Completely inflexible, but that is what you want in this case.

The PKI is great, but there are times when you really don't want to have to trust a third party...
