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).
