2020-01-25upstream: ssh-keygen -Y find-principals fixes based on feedbackdjm@openbsd.org
from Markus: use "principals" instead of principal, as allowed_signers lines may list multiple. When the signing key is a certificate, emit only principals that match the certificate principal list. NB. the command -Y name changes: "find-principal" => "find-principals" ok markus@ OpenBSD-Commit-ID: ab575946ff9a55624cd4e811bfd338bf3b1d0faf

2019-11-25upstream: Add new structure for signature optionsdjm@openbsd.org
This is populated during signature verification with additional fields that are present in and covered by the signature. At the moment, it is only used to record security key-specific options, especially the flags field. with and ok markus@ OpenBSD-Commit-ID: 338a1f0e04904008836130bedb9ece4faafd4e49
2019-11-01upstream: Refactor signing - use sshkey_sign for everything,djm@openbsd.org
including the new U2F signatures. Don't use sshsk_ecdsa_sign() directly, instead make it reachable via sshkey_sign() like all other signature operations. This means that we need to add a provider argument to sshkey_sign(), so most of this change is mechanically adding that.

2019-09-03upstream: sshsig: lightweight signature and verification abilitydjm@openbsd.org
for OpenSSH This adds a simple manual signature scheme to OpenSSH. Signatures can be made and verified using ssh-keygen -Y sign|verify Signatures embed the key used to make them. At verification time, this is matched via principal name against an authorized_keys-like list of allowed signers. Mostly by Sebastian Kinne w/ some tweaks by me ok markus@ OpenBSD-Commit-ID: 2ab568e7114c933346616392579d72be65a4b8fb
