I looks like we’ve come to WG consensus that the sect571r1 curve should be removed from the TLS 1.3 & 4492bis drafts. spt On Jul 20, 2015, at 09:08, Hubert Kario wrote: > On Wednesday 15 July 2015 22:42:54 Dave Garrett wrote: >> On Wednesday, July 15, 2015 09:42:51 pm Dan Brown wrote: >>> What

Hi Folks, This is the Working Group last call for draft-ietf-tls-cached-info-19. This document has undergone modification since last WGLC so another WGLC is appropriate. This document is a dependency for the DICE working group TLS/DTLS profile. Please send your comments to the TLS list by Septemb

[TLS] Adding a new signature scheme

2015-08-06 Thread Ilari Liusvaara
This is about adding a new signature primitive (such as the (eventual) CFRG scheme). There are basically two issues: 1) Do we allocate new ciphersuite codepoints or not? So far each certificate algorithm in ciphersuite has corresponded to only one signature algorithm. Implications of new codepoi
