any relevant certification practice statement;
notice of the revocation or suspension of its certification authority certificate; and
any other fact that materially and adversely affects either the reliability of a certificate that the authority has issued or the authority’s ability to perform its services.

the information in the certificate to be issued is accurate;
the prospective subscriber rightfully holds the private key corresponding to the public key to be listed in the certificate;
the prospective subscriber holds a private key capable of creating a digital signature; and

—(1) By issuing a certificate, a certification authority represents to any person who reasonably relies on the certificate or a digital signature verifiable by the public key listed in the certificate that the certification authority has issued the certificate in accordance with any applicable certification practice statement incorporated by reference in the certificate, or of which the relying person has notice.
(2) In the absence of such certification practice statement, the certification authority represents that it has confirmed that —

the subscriber listed in the certificate;
a person duly authorised to act for that subscriber; or
a person acting on behalf of that subscriber, who is unavailable.
