Windows Secure Shell Client With Support For Smart Cards, Certificates, & FIDO Keys

Project mention: NIST: Personal Identity Verification (PIV) of Federal Employees and Contractors | news.ycombinator.com | 2024-03-23

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.
