2020-08-27upstream: Request PIN ahead of time for certain FIDO actionsdjm@openbsd.org

2020-08-27upstream: support for user-verified FIDO keysdjm@openbsd.org
FIDO2 supports a notion of "user verification" where the user is required to demonstrate their identity to the token before particular operations (e.g. signing). Typically this is done by authenticating themselves using a PIN that has been set on the token. This adds support for generating and using user verified keys where the verification happens via PIN (other options might be added in the future, but none are in common use now). Practically, this adds another key generation option "verify-required" that yields a key that requires a PIN before each authentication. feedback markus@ and Pedro Martelletto; ok markus@ OpenBSD-Commit-ID: 57fd461e4366f87c47502c5614ec08573e6d6a15

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

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
