Certificate management refers to the systematic process of creating, deploying, managing, and revoking digital certificates. These certificates, often adhering to standards like X.509, are fundamental to establishing trust and security in digital communications. They bind a public key to an identity, such as a person, organization, or device, allowing for secure authentication and encryption.

The lifecycle of a digital certificate involves several key stages. Issuance begins with a certificate authority (CA) verifying the identity of the applicant before issuing the certificate. Deployment involves integrating the certificate into the relevant systems, applications, or devices. Ongoing management encompasses tasks like monitoring certificate expiration dates to prevent service disruptions, renewing certificates before they expire, and updating them as needed. Finally, revocation is the process of invalidating a certificate before its scheduled expiration, typically due to a compromised private key or a change in the entity's status.

Effective certificate management is crucial for various security functions. It underpins secure website connections (SSL/TLS), enables secure email communication (S/MIME), facilitates device authentication in networks, and secures code signing. Without proper management, organizations risk security breaches, service outages, and loss of trust. Automated certificate management solutions are increasingly employed to streamline these processes, reduce manual errors, and enhance overall security posture.
