Kleopatra is KDE’s graphical application for managing OpenPGP and X.509 certificates. It provides a desktop interface for working with GnuPG, allowing users to encrypt and decrypt files, create digital signatures and manage cryptographic keys.
The application supports both OpenPGP and S/MIME, making it suitable for personal file encryption and environments that rely on certificate-based security. Its certificate management capabilities extend to key generation, importing and exporting certificates, retrieving public keys from directory services and managing smartcards. A built-in Notepad also provides a convenient way to encrypt and decrypt short pieces of text.
This is free and open source software.
