RFC 9163
Title: Expect-CT Extension for HTTP
Author: E. Stark
Status: Experimental
Stream: IETF
Date: June 2022
Mailbox: estark@google.com
Pages: 18
Updates/Obsoletes/SeeAlso: None
I-D Tag: draft-ietf-httpbis-expect-ct-08.txt
URL: https://www.rfc-editor.org/info/rfc9163
DOI: 10.17487/RFC9163
This document defines a new HTTP header field named "Expect-CT",
which allows web host operators to instruct user agents (UAs) 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 (CT)
deployments. Further, web host operators can use Expect-CT to ensure
that if a UA that supports Expect-CT accepts a misissued certificate,
that certificate will be discoverable in Certificate Transparency
logs.
This document is a product of the HTTP Working Group of the IETF.
EXPERIMENTAL: This memo defines an Experimental Protocol for the
Internet community. It does not specify an Internet standard of any
kind. Discussion and suggestions for improvement are requested.
Distribution of this memo is unlimited.
