Hi, So I finally have time to test the u2f support but so far I haven't been very successful, Specifically, current HEAD has SSH_SK_VERSION_MAJOR 0x00040000 and I can't seem to find a matching libfido2 version, current HEAD of Yubico/libfido2 is 0x00020000 Is there a more up to date libfido2 or a particular commit of openssh-portable I should be using? thanks Sean

Hello, I'm helping the Git for windows team and contributing in git-for-windows repository to help expand the OpenSSH support for fido2 devices on Windows. Currently we are using your internal implementation(sk-usbhic.c) however since Windows 10 version 1903 this requires administrator privileges. I'm trying to create a module for OpenSSH to use webauthn.dll instead of direct calling to

Hi, Sometimes, users might find that the `ssh-sk-helper` crashes after enrolling a new key when using external SK libraries. Currently, the memory returned by SK APIs is freed by the host, but external libraries may have their own methods of handling memory. For instance some external libraries are linked against a foreign libc statically. As a result, the `ssh-sk-helper` would have issues if

I was recently looking at verifying the attestation data (ssh-sk-attest-v00) for a SK key, but I believe the data saved in this structure is insufficient for completing verification of the attestation. While the structure has enough information for U2F devices, FIDO2 devices sign their attestation over a richer "authData" blob [1] (concatenated with the challenge hash). The authData blob

...okens. * ssh-keygen(1): the format of the attestation information optionally recorded when a FIDO key is generated has changed. It now includes the authenticator data needed to validate attestation signatures. * The API between OpenSSH and the FIDO token middleware has changed and the SSH_SK_VERSION_MAJOR version has been incremented as a result. Third-party middleware libraries must support the current API version (7) to work with OpenSSH 8.4. * The portable OpenSSH distribution now requires automake to rebuild the configure script and supporting files. This is not required when simpl...
