This reversible status can be used to note the temporary invalidity of the certificate (e.g., if the user is unsure if the private key has been lost). If, in this example, the private key was found and nobody had access to it, the status could be reinstated, and the certificate is valid again, thus removing the certificate from future CRLs.
Alice and Bob have public key certificates issued by Carol, the certificate authority (CA).; Alice wishes to perform a transaction with Bob and sends him her certificate. Bob, concerned that Alice's private key may have been compromised, creates an 'OCSP request' that contains Alice's certificate serial number and sends it to Carol.
RFC 6961 defines a Multiple Certificate Status Request extension, which allows a server to send multiple OCSP responses in the TLS handshake. A draft proposal for an X509v3 extension field, which expired in April 2013, specified that a compliant server presenting a certificate carrying the extension must return a valid OCSP token in its ...
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 .
ACME logo. The Automatic Certificate Management Environment (ACME) protocol is a communications protocol for automating interactions between certificate authorities and their users' servers, allowing the automated deployment of public key infrastructure at very low cost.

Certificate Transparency (CT) is an Internet security standard for monitoring and auditing the issuance of digital certificates. [1] When an internet user interacts with a website, a trusted third party is needed for assurance that the website is legitimate and that the website's encryption key is valid.
In the standardized algorithm, the following steps are performed for each certificate in the path, starting from the trust anchor. If any check fails on any certificate, the algorithm terminates and path validation fails. (This is an explanatory summary of the scope of the algorithm, not a rigorous reproduction of the detailed steps.)
