Answer 1

Answer: Online Certificate Status Protocol (OCSP)

Step-by-step explanation:

Hi, an Online Certificate Status Protocol (OCSP) is an internet protocol used (normally by web browsers) to determine the status of a digital certificate, for example a SSL certificate supplied by HTTPS sites.

The process is simple:

The OCSP client receives the certificate and sends it to an OSCP responder operated by the certificate authority, and receives a signed response (valid or revoked).
