* upstream: Better handle FIDO keys on tokens that provide userdjm@openbsd.org2021-11-031-2/+2
| | | | | | | | | | | | | | | | | | | | | verification (UV) on the device itself, including biometric keys. Query the token during key creation to determine whether it supports on-token UV and, if so, clear the SSH_SK_USER_VERIFICATION_REQD flag in the key so that ssh(1) doesn't automatically prompty for PIN later. When making signatures with the key, query the token's capabilities again and check whether the token is able (right now) to perform user- verification without a PIN. If it is then the PIN prompt is bypassed and user verification delegated to the token. If not (e.g. the token is biometric capable, but no biometric are enrolled), then fall back to user verification via the usual PIN prompt.

| | | | | | | | | | | When downloading a resident, verify-required key from a FIDO token, preserve the verify-required in the private key that is written to disk. Previously we weren't doing that because of lack of support in the middleware API. from Pedro Martelletto; ok markus@ and myself OpenBSD-Commit-ID: 201c46ccdd227cddba3d64e1bdbd082afa956517

* upstream: changes to support FIDO attestationdjm@openbsd.org2020-01-291-5/+5
| | | | | | | | | | | | | | | 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

* upstream: Extends the SK API to accept a set of key/value optionsdjm@openbsd.org2020-01-061-17/+104
| | | | | | | | | | | | | | | | | | | | 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
