Abstract

The Ed25519 [Ed25519] signature algorithm, specifically Ed25519-SHA-512, has been implemented in OpenSSH. RFC 4255 [RFC4255] defines a DNS resource record, "SSHFP", which can be used to publish a fingerprint of the SSH server public key in the DNS. This document updates the IANA "SSHFP RR Types for public key algorithms" registry by adding an algorithm number for Ed25519 [Ed25519].
