Technical Summary
This document defines a new HTTP header field, named Expect-CT, that allows web host operators
to instruct user agents to expect valid Signed Certificate Timestamps (SCTs) to be served on
connections to these hosts. Expect-CT allows web host operators to discover misconfigurations in
their Certificate Transparency deployments and ensure that misissued certificates accepted by UAs
are discoverable in Certificate Transparency logs.
