The openpgp-card-tools-git package (formerly oct-git) provides a specialized tooling for Git signing and verification using OpenPGP cards. It focuses on making hardware-backed cryptographic operations seamless within Git workflows. This tool ensures that developers can easily use their security tokens or smart cards to sign commits and verify signatures, providing a higher level of security for source code integrity through hardware-protected private keys.

The openpgp-card-tools package provides a set of command-line utilities for interacting with OpenPGP cards. It supports common operations such as listing card information, managing PINs, generating keys, and performing cryptographic operations directly on the hardware. The primary tool, 'oct', serves as a versatile interface for administrative tasks and user-level card management, ensuring secure handling of private keys stored on OpenPGP-compliant smart cards and security tokens.
