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 ...
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 an ...
This requirement of on-line validation negates one of the original major advantages of PKI over symmetric cryptography protocols, namely that the certificate is "self-authenticating". Symmetric systems such as Kerberos also depend on the existence of on-line services (a key distribution center in the case of Kerberos).
Internet securityprotocols. DNS-based Authentication of Named Entities (DANE) is an Internet security protocol to allow X.509 digital certificates, commonly used for Transport Layer Security (TLS), to be bound to domain names using Domain Name System Security Extensions (DNSSEC). [1]
PKCS 1. In cryptography, PKCS #1 is the first of a family of standards called Public-Key Cryptography Standards (PKCS), published by RSA Laboratories. It provides the basic definitions of and recommendations for implementing the RSA algorithm for public-key cryptography. It defines the mathematical properties of public and private keys ...
The Certificate Management Protocol (CMP) is an Internet protocol standardized by the IETF used for obtaining X.509 digital certificates in a public key infrastructure (PKI). CMP is a very feature-rich and flexible protocol, supporting many types of cryptography. CMP messages are self-contained, which, as opposed to EST, makes the protocol ...
Microsoft PFX file format. In cryptography, PKCS #12 defines an archive file format for storing many cryptography objects as a single file. It is commonly used to bundle a private key with its X.509 certificate or to bundle all the members of a chain of trust. A PKCS #12 file may be encrypted and signed. The internal storage containers, called ...
