This is a relatively small rev from -02, with more clarity on key limits and mitigation of Triple Handshake (extended_master_secret). 

Our open issues are at https://github.com/yaronf/I-D/issues - fell free to comment or open new ones.

Thanks!

	Peter, Thomas and Yaron

    Abstract:
       Transport Layer Security (TLS) and Datagram Transport Layer Security
       (DTLS) are widely used to protect data exchanged over application
       protocols such as HTTP, SMTP, IMAP, POP, SIP, and XMPP.  Over the
       last few years, several serious attacks on TLS have emerged,
       including attacks on its most commonly used cipher suites and their
       modes of operation.  This document provides recommendations for
       improving the security of deployed services that use TLS and DTLS.
       The recommendations are applicable to the majority of use cases.

       This document was published as RFC 7525 when the industry was in the
       midst of its transition to TLS 1.2.  Years later this transition is
       largely complete and TLS 1.3 is widely available.  Given the new
       environment, we believe new guidance is needed.
