A digital certificate certifies the ownership of a public key by the named subject of the certificate. This allows others (relying parties) to rely upon signatures or on assertions ...
In cryptography, X.509 is an International Telecommunication Union (ITU) standard defining the format of public key certificates. [1] 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 ...
Public key infrastructure. A public key infrastructure ( PKI) is a set of roles, policies, hardware, software and procedures needed to create, manage, distribute, use, store and revoke digital certificates and manage public-key encryption. The purpose of a PKI is to facilitate the secure electronic transfer of information for a range of network ...
Public key certificate. 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 ...
An offline root certificate authority is a certificate authority (as defined in the X.509 standard and RFC 5280) which has been isolated from network access, and is often kept in a powered-down state. In a public key infrastructure, the chain of trusted authorities begins with the root certificate authority (root CA).
