The new ISRG Root X2 is cross-signed with ISRG Root X1, Let's Encrypt's own root certificate. Let's Encrypt did not issue an OCSP responder for the new intermediate certificates and instead plans to rely solely on certificate revocation lists (CRLs) to recall compromised certificates and short validity periods to reduce danger of certificate ...
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.

The OCSP responder uses the certificate serial number to look up the revocation status of Alice's certificate. The OCSP responder looks in a CA database that Carol maintains. In this scenario, Carol's CA database is the only trusted location where a compromise to Alice's certificate would be recorded.
A domain validated certificate for opensuse.org, issued by Let's Encrypt. A domain validated certificate (DV) is an X.509 public key certificate typically used for Transport Layer Security (TLS) where the domain name of the applicant is validated by proving some control over a DNS domain. [1]
The certificate is also a confirmation or validation by the CA that the public key contained in the certificate belongs to the person, organization, server or other entity noted in the certificate. A CA's obligation in such schemes is to verify an applicant's credentials, so that users and relying parties can trust the information in the issued ...
Certificates that support certificate transparency must include one or more signed certificate timestamps (SCTs), which is a promise from a log operator to include the certificate in their log within a maximum merge delay (MMD). [4] [3] At some point within the maximum merge delay, the log operator adds the certificate to their log.
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 ...
