PuTTY CAC adds the ability to use the Windows Certificate API (CAPI), Public Key Cryptography Standards (PKCS) libraries, or Fast Identity Online (FIDO) keys to perform SSH public key authentication using a private key associated with a certificate that is stored on a hardware token.nnPuTTY CAC can be used with many types of cryptographic tokens such as Yubikeys and popular smart card models. The 'CAC' in 'PuTTY CAC' refers to Common Access Card, a smart card token used for US Government facilities which was one of the initial drivers for the development of PuTTY CAC.
