Binary package “monkeysphere” in ubuntu precise

leverage the OpenPGP web of trust for SSH and TLS authentication

 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).
