Explanation

A digital certificate (such as an SSL/TLS server certificate) is essentially a public key that has been digitally signed by a Certificate Authority (CA) to verify its authenticity and bind it to a specific identity (e.g., a domain name). When a server presents its certificate, it is presenting its public key along with proof of identity. The private key (C) is kept secret and never shared. A CRL (B) is a Certificate Revocation List used to check if a certificate has been revoked. A recovery agent (D) is a PKI role used for key recovery, not synonymous with a certificate.
