2020-09-09upstream: when writing an attestation blob for a FIDO key, record alldjm@openbsd.org
the data needed to verify the attestation. Previously we were missing the "authenticator data" that is included in the signature. spotted by Ian Haken feedback Pedro Martelletto and Ian Haken; ok markus@ OpenBSD-Commit-ID: 8439896e63792b2db99c6065dd9a45eabbdb7e0a
2020-08-27upstream: preserve verify-required for resident FIDO keysdjm@openbsd.org
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
2020-05-01upstream: when signing a challenge using a FIDO toke, perform thedjm@openbsd.org
hashing in the middleware layer rather than in ssh code. This allows middlewares that call APIs that perform the hashing implicitly (including Microsoft's AFAIK). ok markus@ OpenBSD-Commit-ID: c9fc8630aba26c75d5016884932f08a5a237f37d

2020-02-07upstream: Replace "security key" with "authenticator" in programnaddy@openbsd.org
messages. This replaces "security key" in error/usage/verbose messages and distinguishes between "authenticator" and "authenticator-hosted key". ok djm@ OpenBSD-Commit-ID: 7c63800e9c340c59440a054cde9790a78f18592e
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
2020-01-26upstream: improve the error message for u2f enrollment errors bydjm@openbsd.org
making ssh-keygen be solely responsible for printing the error message and convertint some more common error responses from the middleware to a useful ssherr.h status code. more detail remains visible via -v of course. also remove indepedent copy of sk-api.h declarations in sk-usbhid.c and just include it. feedback & ok markus@ OpenBSD-Commit-ID: a4a8ffa870d9a3e0cfd76544bcdeef5c9fb1f1bb

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
2019-12-30upstream: translate and return error codes; retry on bad PINdjm@openbsd.org
Define some well-known error codes in the SK API and pass them back via ssh-sk-helper. Use the new "wrong PIN" error code to retry PIN prompting during ssh-keygen of resident keys. feedback and ok markus@ OpenBSD-Commit-ID: 9663c6a2bb7a0bc8deaccc6c30d9a2983b481620

2019-12-30upstream: SK API and sk-helper error/PIN passingdjm@openbsd.org
Allow passing a PIN via the SK API (API major crank) and let the ssh-sk-helper API follow. Also enhance the ssh-sk-helper API to support passing back an error code instead of a complete reply. Will be used to signal "wrong PIN", etc. feedback and ok markus@ OpenBSD-Commit-ID: a1bd6b0a2421646919a0c139b8183ad76d28fb71
2019-12-30upstream: resident keys support in SK APIdjm@openbsd.org
Adds a sk_load_resident_keys() function to the security key API that accepts a security key provider and a PIN and returns a list of keys. Implement support for this in the usbhid middleware. feedback and ok markus@ OpenBSD-Commit-ID: 67e984e4e87f4999ce447a6178c4249a9174eff0

2019-12-14upstream: use ssh-sk-helper for all security key signing operationsdjm@openbsd.org
This extracts and refactors the client interface for ssh-sk-helper from ssh-agent and generalises it for use by the other programs. This means that most OpenSSH tools no longer need to link against libfido2 or directly interact with /dev/uhid* requested by, feedback and ok markus@ OpenBSD-Commit-ID: 1abcd3aea9a7460eccfbf8ca154cdfa62f1dc93f
