Expiration dates play a key role in this process, acting as a built-in check that prompts users to review and renew their certificates periodically. + Certificates are composites of components that are linked together using [signatures](../signing_components). A certificate can be valid or invalid as a whole. However, even when a certificate is valid, individual components (subkeys or identities) of it can be invalid.
