DESCRIPTION
gpg-card is a GnuPG tool for managing OpenPGP and PIV smartcards. It provides an interactive interface for configuring cards, managing PINs, generating keys, and transferring keys to smartcards.
Introduced in GnuPG 2.3 as a replacement for the older gpg --card-edit workflow, it offers a more streamlined command-line experience for smartcard operations.
