* upstream: support for user-verified FIDO keysdjm@openbsd.org2020-08-271-3/+19
| | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | | | 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.

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
