These are test keys *NOT* to be used in production. The `certificate_hierarchy_1` and `certificate_hierarchy_2` contain two disjoint but similarly organized certificate hierarchies. Each contains: * The respective root CA cert in `certs/ca.cert.pem` * The intermediate CA cert in `intermediate/certs/intermediate.cert.pem`, signed by the root CA * A client cert and a server cert--both signed by the intermediate CA--in `intermediate/certs/client.cert.pem` and `intermediate/certs/localhost-1.cert.pem`; the corresponding keys are in `intermediate/private`
