In public key infrastructure (PKI) systems, a certificate signing request (CSR or certification request) is a message sent from an applicant to a certificate authority of the public key infrastructure (PKI) in order to apply for a digital identity certificate. The CSR usually contains the public key for which the certificate should be issued ...
The Online Certificate Status Protocol (OCSP) is an Internet protocol used for obtaining the revocation status of an X.509 digital certificate. [2] It is described in RFC 6960 and is on the Internet standards track.
In practice, a web site operator obtains a certificate by applying to a certificate authority with a certificate signing request. The certificate request is an electronic document that contains the web site name, company information and the public key.

Let's Encrypt developers planned to generate an ECDSA root key back in 2015, [44] but then pushed back the plan to early 2016, then to 2019, and finally to 2020. On September 3, 2020, Let’s Encrypt issued six new certificates: one new ECDSA root named "ISRG Root X2", four intermediates, and one cross-sign.
The Enrollment over Secure Transport, or EST is a cryptographic protocol that describes an X.509 certificate management protocol targeting public key infrastructure (PKI) clients that need to acquire client certificates and associated certificate authority (CA) certificates.

(LGPL licensed) XiPKI, [36] CA and OCSP responder. With SHA-3 support, implemented in Java. (Apache licensed) XCA [37] is a graphical interface, and database. XCA uses OpenSSL ...
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.
For example, when Apache queries the OCSP server, in the event of a temporary failure, it will discard the cached good response from the previous request, and start serving the bad response. [19] Nginx performs lazy loading of OCSP responses, which means that for the first few web requests it is unable to add the OCSP response.
