git-credential-keepassxc is a Rust-based Git credential helper that enables Git and shell scripts to store and retrieve credentials from KeePassXC. It implements the KeePassXC browser protocol to communicate with the password manager via socket/named pipe interfaces. The application provides subcommands for getting credentials (get), generating TOTP codes (totp), storing credentials (store), managing configuration (configure), verifying caller identity (caller), and other auxiliary functions. It features optional security enhancements including strict caller verification, YubiKey-based encryption of configuration files, and desktop notifications. The architecture follows a modular Rust CLI pattern with clear separation between argument parsing, configuration management, core protocol implementation, and utility functions.
