Hello, Stephen and I posted the draft below to see if the TLS working group is ready to take steps to deprecate TLSv1.0 and TLSv1.1. There has been a recent drop off in usage for web applications due to the PCI Council recommendation to move off TLSv1.0, with a recommendation to go to TLSv1.2 by June 30th. NIST has also been recommending TLSv1.2 as a baseline. Applications other than those using HTTP may not have had the same reduction in usage. If you are responsible for services where you have a reasonable vantage point to gather and share statistics to assess usage further, that could be helpful for the discussion. We've received some feedback that has been incorporated into the working draft and feelers in general have been positive. It would be good to know if there are any show stoppers that have not been considered.

Name: draft-moriarty-tls-oldversions-diediedie Revision: 00 Title: Deprecating TLSv1.0 and TLSv1.1 Document date: 2018-06-18 Group: Individual Submission Pages: 10 URL: https://www.ietf.org/internet-drafts/draft-moriarty-tls-oldversions-diediedie-00.txt Status: https://datatracker.ietf.org/doc/draft-moriarty-tls-oldversions-diediedie/ Htmlized: https://tools.ietf.org/html/draft-moriarty-tls-oldversions-diediedie-00 Htmlized: https://datatracker.ietf.org/doc/html/draft-moriarty-tls-oldversions-diediedie Abstract: This document [if approved] formally deprecates Transport Layer Security (TLS) versions 1.0 [RFC2246] and 1.1 [RFC4346] and moves these documents to the historic state. These versions lack support for current and recommended cipher suites, and various government and industry profiiles of applications using TLS now mandate avoiding these old TLS versions. TLSv1.2 has been the recommended version for IETF protocols since 2008, providing sufficient time to transition away from older versions. Products having to support older versions increase the attack surface unnecessarily and increase opportunities for misconfigurations. Supporting these older versions also requires additional effort for library and product maintenance. This document updates the backward compatibility sections of TLS RFCs [[list TBD]] to prohibit fallback to TLSv1.0 and TLSv1.1. This document also updates RFC 7525. Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.
