sequoia-keystore-openpgp-card

An openpgp card backend for Sequoia's private key store.

The sequoia-keystore crate implements a server that manages secret keys. Secret key material can be stored in files, on hardware devices like smartcards, or accessed via the network. sequoia-keystore doesn't implement these access methods. This is taken care of by various backends.

This crate includes a backend that exposes the secret keys managed by OpenPGP cards. It uses PCSC in order to access the cards. On Linux distributions, this means that you'll need to install a PCSC service like PC/CS Lite. On Debian this is provided by the pcscd package.
