    PuTTY-CAC was an interesting, although imperfect solution to using PIV/CAC cards together with SSH. I remember piloting it from 2013-2014 at an agency. Back then, it was maintained by Dan Risacher[0]. Nowadays it is maintained on GitHub[1] and adopted some interesting features like FIDO.

    >so I've been working on extending our support for hardware-backed SSH certificates to Windows

    Interesting work & I wish him luck. The ability to use hardware SSH certs on Windows has been around for at least a decade now, but it hasn't been a seamless experience.

    The other attempt I'm aware of is PuTTY-CAC[0]. The issue with PuTTY-CAC is that the server still needs to be configured to check the certificate against CRLs & PKI infrastructure. Even without that, it is still used in security-conscious organizations, like the US Department of Veteran Affairs [1], for example.

    There is a GitHub Issue by me which may be interesting for you... it is about PuTTY CAC, but maybe you find some useful information in that too.
  • How to secure SSH for Remote connections
    1 project | /r/sysadmin | 1 Aug 2022
    If you have smartcards or FIDO2 security keys (Yubikeys), consider using something like PuTTY CAC (https://github.com/NoMoreFood/putty-cac) to provide cheap and easy multi-factor authentication. With FIDO2, specifically, you can force the SSH server to only accept security keys by setting the only allowed authentication method to be [[email protected]](mailto:[email protected]).

    2) Get an SSH client which works with Windows. I'd like to suggest or a fork based on "Putty SSH" ( https://www.putty.org/ ) called "Putty CAC" (SSH) which as of late May 2022 also supports FIDO2 keys ( citation: https://github.com/NoMoreFood/putty-cac/issues/57 ) ( Site for Putty CAC (ssh): https://github.com/NoMoreFood/putty-cac ) (unlike the main Putty SSH as of July 22, 2022)
  • Single SSH key-pair for my local machine and all my remote servers? Or a custom SSH key-pair for each remote server?

    If you want to be safer, look into using WebAuthn/FIDO2 hardware token. OpenSSH supports them since version 8.2, and if you're on Windows, putty-cac added support in the last release.

  • Call For Testers: PuTTY CAC 0.77 Pre-Release (FIDO Support)
    1 project | /r/sysadmin | 4 May 2022
    For several years, I've been the lead developer for a fork of PuTTY called PuTTY CAC that focuses on 2FA. In addition to utilizing certificate-bound keypairs (via Windows CAPI or a PKCS library), I've recently added support for FIDO2 keys using the WebAuthn functionality in Windows 10+. I tentatively plan on releasing these changes shortly after upstream PuTTY 0.77 is released. The development branch binaries can be found here: putty-cac/binaries at fido_dev_branch · NoMoreFood/putty-cac (github.com).
