Class Method Details

.cert_roles ⇒ Array<Symbol>

All known CNML certificate roles.

Returns:

  • (Array<Symbol>)

def self.cert_roles

end

.missing_extensions(_cert) ⇒ Array<String>

Validate that a certificate has the required CNML extensions. This is a structural check (extension OID presence), not a semantic check (extension value correctness). Full validation requires the OIML R 76 specification.

Parameters:

  • cert (Confium::PKI::Certificate) —

    the cert to check

Returns:

  • (Array<String>) —

    list of missing required extension OIDs

def self.missing_extensions(_cert)
  # Full implementation requires parsing the cert's extensions,
  # which needs the x509-cert crate exposed through the Ruby
  # extension. For now, returns an empty array (no validation).
  #
  # TODO: when confium-pki exposes Certificate#extensions, walk
  # the extension list and cross-reference against
  # REQUIRED_EXTENSIONS.
  []

.optional_extension_oids ⇒ Array<String>
