Subject: The entity a certificate belongs to: a machine, an individual, or an organization. Issuer: The entity that verified the information and signed the certificate.

The owner of the key pair makes the public key available to anyone, but keeps the private key secret. A certificate verifies that an entity is the owner of a particular public key. Certificates that follow the X. 509 standard contain a data section and a signature section.

Assumption: A link certificate is used, when an old certificate is replaced by a new one. The link certificate is the new certificate signed with the old private key. So that with the old public key, the new certificate could be verified.

A PKI certificate is a trusted digital identity. It is used to identify users, servers or things when communicating over untrusted networks, to sign code or documents and to encrypt data or communication. A PKI certificate is also called a digital certificate.

The most familiar use of PKI is in SSL certificates. SSL (Secure Sockets Layer) is the security protocol used on the web when you fetch a page whose address begins with https: . TLS (Transport Layer Security) is a newer version of the protocol.

Common examples of PKI security today are SSL certificates on websites so that site visitors know they're sending information to the intended recipient, digital signatures, and authentication for Internet of Things devices.

Single domain is a certificate that authenticates one domain. Wildcard is a certificate that authenticates one domain and an unlimited number of its subdomains. Multi-domain is a certificate that authenticates multiple domains.

One of the most common uses of PKI is the TLS/SSL (transport layer security/secure socket layer), which secures encrypted HTTP (hypertext transfer protocol) communications. Website owners will obtain a digital certificate from a trusted CA.

Certificates also enable secure, confidential communication between two entities. There are different kinds of certificates, such as personal certificates, used by individuals, and server certificates, used to establish secure sessions between the server and clients through secure sockets layer (SSL) technology.

There are three types of SSL Certificate available today; Extended Validation (EV SSL), Organization Validated (OV SSL) and Domain Validated (DV SSL). The encryption levels are the same for each certificate, what differs is the vetting and verification processes needed to obtain the certificate.
