In cryptography, a public key certificate, also known as a digital certificate or identity certificate, is an electronic document used to prove the validity of a public key. [ 1 ] [ 2 ] The certificate includes the public key and information about it, information about the identity of its owner (called the subject), and the digital signature of ...
TLS and SSL do not fit neatly into any single layer of the OSI model or the TCP/IP model. [4] [5] TLS runs "on top of some reliable transport protocol (e.g., TCP)," [6]: §1 which would imply that it is above the transport layer. It serves encryption to higher layers, which is normally the function of the presentation layer.

The Online Certificate Status Protocol (OCSP) is an Internet protocol used for obtaining the revocation status of an X.509 digital certificate. [2] It is described in RFC 6960 and is on the Internet standards track.
X.509 certificates are used in many Internet protocols, including TLS/SSL, which is the basis for HTTPS, [2] the secure protocol for browsing the web. They are also used in offline applications, like electronic signatures. [3] An X.509 certificate binds an identity to a public key using a digital signature.
