summary: PuTTY could use RSA keys held on smartcards
class: wish: This is a request for an enhancement.
difficulty: taxing: Needs external things we don't have (standards, users etc)
priority: low: We aren't sure whether to fix this or not.

It's been suggested that PuTTY could use RSA keys held on a smartcard for authentication. This would require interfacing with smartcard APIs and suchlike, and might be an application for the MDPI.

Alternatively, it might be better to integrate smartcard support into an SSH agent, either as part of Pageant or as a plug-in replacement for it. After all, the purpose of a smartcard is to generate cryptographic signatures on demand, which is what an SSH agent does too.
