Where Websites Come To Life
What is Certificate Authority (CA)?
Posted: May 14th, 2018
An entity that issues a digital certificate to the SSL seeker is dubbed as a certificate authority (CA). As a part of a public key infrastructure, a CA checks the credentials or information with registration authority (an authority who verifies SSL seeker’s request and tells the CA to issue the certificate) provided by the SSL seeker. If the registration authority verifies the information, then the CA issues a certificate to the requester of a digital certificate.
The certificate includes website owner information, public key, certificate expiry date, owner’s name, and other information depending upon type of SSL certificate. When a server makes a handshake with the client’s browser, the client will try to verify the signature against a listed CAs. Web browser comes with pre-installed lists of CAs.
