The IESG has approved the following document: - 'Expect-CT Extension for HTTP' (draft-ietf-httpbis-expect-ct-08.txt) as Experimental RFC This document is the product of the Hypertext Transfer Protocol Working Group. The IESG contact persons are Adam Roach, Alexey Melnikov and Ben Campbell. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-httpbis-expect-ct/ 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. Working Group Summary This document did not see a tremendous amount of discussion after the Working Group agreed to adopt it, but did see a number of reviews from within the community. Given its intended status as Experimental, we believe this is appropriate. Document Quality Chrome has shipped an implementation for about 1 year. Personnel Mark Nottingham is the document shepherd. Alexey Melnikov is the responsible Area Director.
