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.
In cryptography, PKCS #11 is a Public-Key Cryptography Standards that defines a C programming interface to create and manipulate cryptographic tokens that may contain secret cryptographic keys. It is often used to communicate with a Hardware Security Module or smart cards .
The most common format for public key certificates is defined by X.509. Because X.509 is very general, the format is further constrained by profiles defined for certain use cases, such as Public Key Infrastructure (X.509) as defined in RFC 5280.
gnoMint is a free software tool for managing X.509 certification authorities (CAs). Its purpose is to offer an easy to use interface for creating certification authorities and all related elements including X.509 digital certificates, certificate signing requests (CSRs) and certificate revocation lists (CRLs).
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.
In computer security, an attribute certificate, or authorization certificate (AC) is a digital document containing attributes associated to the holder by the issuer. [1] When the associated attributes are mainly used for the purpose of authorization, AC is called authorization certificate. AC is standardized in X.509. RFC 5755 further specifies ...
ISO/IEC 6523 "International Code Designator" uses OIDs with the prefix "1.3". In computer security, OIDs serve to name almost every object type in X.509 certificates, such as components of Distinguished Names, CPSs, etc. Within X.500 and LDAP schemas and protocols, OIDs uniquely name each attribute type and object class, and other elements of ...
A certificate policy (CP) is a document which aims to state what are the different entities of a public key infrastructure (PKI), their roles and their duties. This document is published in the PKI perimeter. When in use with X.509 certificates, a specific field can be
