CASTLE Certification Authority

CASTLE contains its own Certification Authority (CA). The root CA is CASTLE Root CA and it has several intermediate CA:

  • License CA: manages certificates related with the CASTLE Licensing system.
  • Web CA: manages web certificates.
  • VPN CA: manages certificates generated to access to CASTLE Virtual Private Network (VPN).

CASTLE also runs an OCSP responder to cross check the status of a given certificate.
