Online Certificate Status Protocol

The Online Certificate Status Protocol (OCSP) is a method used to check the validity of digital certificates in real-time. Digital certificates are like online ID cards that verify the identity of websites and other entities. OCSP allows your device to ask a certificate authority (the issuer of the certificate) whether a specific certificate is still valid or has been revoked. This helps ensure secure online transactions and communications, as it confirms that the website you’re interacting with hasn't been compromised or is fraudulent, enhancing trust and safety in the digital environment.
