This is an implementation for a REST-style revoke infrastructure. This contains both the code of the crate "edcert-restrevoke", which is the client implementation (fully rust) and also a sample implementation of a server (found in revoke-server), which is a simple PHP script querying a MySQL database.

The architecture is as follows: You can have multiple "clients", which all connect to one (or more) revoke-server. These can query if a certain public key has been revoked, or not. The server will eg. query a database for public keys known to be revoked and send an appropriate response.

A public key and therefore a certificate will be revoked, if the private key has been disclosed, or the authenticity can't be guaranteed for other reason
