Server

Enable Certificate Transparency for HTTPS

erver operators can deliver SCTs by using a special TLS extension (see figure 2). In this case, the CA issues the certificate to the server operator, and the server operator submits the certificate to the log. The log sends the SCT to the server operator, and the server operator uses a TLS extension with type signed_certificate_timestamp to deliver the SCT to the client during the TLS handshake.
