"Identity" is the formally correct term, but I think "null" is much clearer than "identity". Especially in the context of certificates, where "identity" can be mistaken for something else. Thanks, Yaron On 04/08/2016 01:29 AM, Yoav Nir wrote: On 7 Apr 2016, at 6:12 PM, Tero Kivinen

Replying to myself... I’ve been told off-list that it didn’t make sense to introduce the hot, new algorithm as a MAY. The only reason I’m suggesting this is that there are currently no implementations to interop with, and no EdDSA certificates where the public keys might come from. My main moti

Hi At the meeting today, I presented the SafeCurves draft status and asked the room whether we wanted to wait for CFRG and Curdle to settle their respective RFCs. The room was unanimously in favor of not having anything in the current draft, instead using RFC 7427 digital signatures. To be cert
