2020-01-29upstream: changes to support FIDO attestationdjm@openbsd.org
Allow writing to disk the attestation certificate that is generated by the FIDO token at key enrollment time. These certificates may be used by an out-of-band workflow to prove that a particular key is held in trustworthy hardware. Allow passing in a challenge that will be sent to the card during key enrollment. These are needed to build an attestation workflow that resists replay attacks. ok markus@ OpenBSD-Commit-ID: 457dc3c3d689ba39eed328f0817ed9b91a5f78f6
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

2020-01-06upstream: Extends the SK API to accept a set of key/value optionsdjm@openbsd.org
for all operations. These are intended to future-proof the API a little by making it easier to specify additional fields for without having to change the API version for each. At present, only two options are defined: one to explicitly specify the device for an operation (rather than accepting the middleware's autoselection) and another to specify the FIDO2 username that may be used when generating a resident key. These new options may be invoked at key generation time via ssh-keygen -O This also implements a suggestion from Markus to avoid "int" in favour of uint32_t for the algorithm argument in the API, to make implementation of ssh-sk-client/helper a little easier. feedback, fixes and ok markus@ OpenBSD-Commit-ID: 973ce11704609022ab36abbdeb6bc23c8001eabc
