Certificate Revocation
Noun · Security & Infosec
Definitions
The invalidation of a certificate before its normal expiration, usually because the private key was compromised, the certificate was misissued, or the subject is no longer trusted. Revocation mechanisms must work quickly enough to matter operationally.
In plain English: Canceling a certificate before it expires because it can no longer be trusted.
Example: "The CA initiated certificate revocation after discovering the key had been exposed in a public repo."
