About:
GCR is a library for GUI crypto UI components, primarily used for secure key and certificate management. It provides the underlying framework for applications like Seahorse, enabling secure interactions with cryptographic tokens and smart cards. Its main value is offering standardized UI dialogs and parsing for cryptographic operations within the GNOME desktop environment.

Key Features:

UI dialogs for PIN entry and key management
Integration with PKCS#11 modules and smart cards
GObject-based API for easy integration into GTK apps
Certificate and key parsing utilities

Use Cases:

Building graphical front-ends for OpenPGP and SSH key management
Integrating smart card authentication into desktop applications
Handling certificate parsing and selection workflows

Alternatives:

libsecret – Libsecret handles secret storage (passwords), while GCR focuses on cryptographic object management and UI.
OpenSSL – OpenSSL is a command-line and library toolkit; GCR provides the GUI layer often missing in raw crypto libraries.
