rpki-client: Features

The global routing system of the internet consists of a number of functionally independent actors (Autonomous Systems) which use BGP (Border Gateway Protocol) to exchange routing information. The system is very dynamic and flexible by design. Connectivity and routing topologies are subject to change. Changes easily propagate globally within a few minutes. One weakness of this system is that these changes cannot be validated against information existing outside of the BGP protocol itself.

To achieve this, it uses a public key infrastructure that creates a chain of resource certificates that follows the same structure as the way IP addresses and AS numbers are handed down.
In order to satisfy those requirements, rpki-client has:
