Explanation:
A Certification Practices Statement (CPS) is a comprehensive document provided by a Certificate Authority (CA) that details the practices and standards the CA employs to issue, manage, revoke, and renew digital certificates. The purpose of a CPS is to ensure trust and security in the digital certificate issuance process by being transparent about the procedures, policies, and security controls that the CA adheres to.
This confidence in digital transactions is crucial for securing online communications and establishing digital identities. A CPS typically includes information about the obligations of the parties involved in the certificate management lifecycle, which include the CA itself, subscribers, and relying parties.
