SSH key-based authentication is tried-and-true, but it lacks a true
Public Key Infrastructure for key certification, revocation and
expiration. Monkeysphere is a framework that uses the OpenPGP web of
trust for these PKI functions. It can be used in both directions:
for users to get validated host keys, and for hosts to authenticate
users. Current monkeysphere SSH tools are designed to integrate
with the OpenSSH implementation of the Secure Shell protocol.
.
Monkeysphere can also be used by a validation agent to validate TLS
connections (e.g. https).
