  2. Certificate revocation list - Wikipedia

    en.wikipedia.org/wiki/Certificate_revocation_list

    In cryptography, a certificate revocation list (CRL) is "a list of digital certificates that have been revoked by the issuing certificate authority (CA) before their scheduled expiration date and should no longer be trusted".

  3. Certificate revocation - Wikipedia

    en.wikipedia.org/wiki/Certificate_revocation

    A certificate revocation list (CRL) enumerates revoked certificates. They are cryptographically authenticated by the issuing CA. [29] CRLs have scalability issues, and rely on the client having enough network access to download them prior to checking a certificate's status. [9]

  4. Online Certificate Status Protocol - Wikipedia

    en.wikipedia.org/wiki/Online_Certificate_Status...

    It was created as an alternative to certificate revocation lists (CRL), specifically addressing certain problems associated with using CRLs in a public key infrastructure (PKI). [3] Messages communicated via OCSP are encoded in ASN.1 and are usually communicated over HTTP.

  5. X.509 - Wikipedia

    en.wikipedia.org/wiki/X.509

    X.509 and RFC 5280 also include standards for certificate revocation list (CRL) implementations. Another IETF-approved way of checking a certificate's validity is the Online Certificate Status Protocol (OCSP). Firefox 3.0 enabled OCSP checking by default, as did versions of Windows from at least Vista and later. [9]

  6. OCSP stapling - Wikipedia

    en.wikipedia.org/wiki/OCSP_stapling

    The Online Certificate Status Protocol (OCSP) stapling, formally known as the TLS Certificate Status Request extension, is a standard for checking the revocation status of X.509 digital certificates. [1]

  7. Validation authority - Wikipedia

    en.wikipedia.org/wiki/Validation_authority

    It must be continuously updated with current CRL information from a certificate authority which issued the certificates contained within the CRL. While this is a potentially labor-intensive process, the use of a dedicated validation authority allows for dynamic validation of certificates issued by an offline root certificate authority .

  8. Certificate policy - Wikipedia

    en.wikipedia.org/wiki/Certificate_policy

    Certificate revocation lists [ edit ] Those lists are a vital part of any public key infrastructure, and as such, a specific chapter is dedicated to the description of the management associated with these lists, to ensure consistency between certificate status and the content of the list.

  9. Public key certificate - Wikipedia

    en.wikipedia.org/wiki/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 digital signature of ...
