                Common YANG Data Types for Cryptography
                   draft-ietf-netconf-crypto-types-14

Abstract

   This document primarily defines a YANG module for identities,
   typedefs, groupings, and RPCs useful to cryptographic applications.
   This draft additionally defines a new IANA registry for cryptographic
   primitives, modifies existing SSH and TLS registries, and defines a
   process enabling IANA to automatically generate three new YANG
   modules from the new cryptographic primitives registry.
