In cryptography and computer security, a root certificate is a public key certificate that identifies a root certificate authority (CA). [2] Root certificates are self-signed (and it is possible for a certificate to have multiple trust paths, say if the certificate was issued by a root that was cross-signed) and form the basis of an X.509 ...
The roles of root certificate, intermediate certificate and end-entity certificate as in the chain of trust. In computer security, a chain of trust is established by validating each component of hardware and software from the end entity up to the root certificate. It is intended to ensure that only trusted software and hardware can be used ...
In cryptographic systems with hierarchical structure, a trust anchor is an authoritative entity for which trust is assumed and not derived. [1]In the X.509 architecture, a root certificate would be the trust anchor from which the whole chain of trust is derived.
As of 24 August 2020, 147 root certificates, representing 52 organizations, are trusted in the Mozilla Firefox web browser, [10] 168 root certificates, representing 60 organizations, are trusted by macOS, [11] and 255 root certificates, representing 101 organizations, are trusted by Microsoft Windows.

The Certification Authority Browser Forum, also known as the CA/Browser Forum, is a voluntary consortium of certification authorities, vendors of web browsers and secure email software, operating systems, and other PKI-enabled applications that promulgates industry guidelines governing the issuance and management of X.509 v.3 digital certificates that chain to a trust anchor embedded in such ...
FreeBSD included CAcert's root certificate but removed it in 2008, following Mozilla's policy. [7] In 2014, CAcert was removed from Ubuntu, [8] Debian, [9] and OpenBSD [10] root stores. In 2018, CAcert was removed from Arch Linux. [11] As of Feb 2022, the following operating systems or distributions include the CAcert root certificate by ...
OpenSSL is a software library for applications that provide secure communications over computer networks against eavesdropping, and identify the party at the other end. It is widely used by Internet servers, including the majority of HTTPS websites.
The certification path validation algorithm is the algorithm which verifies that a given certificate path is valid under a given public key infrastructure (PKI). A path starts with the Subject certificate and proceeds through a number of intermediate certificates up to a trusted root certificate, typically issued by a trusted certificate ...
