About Kleopatra
Kleopatra manages OpenPGP and S/MIME (X.509) certificates and provides a graphical front end for cryptographic tasks. You can create, import and export keys, look up and upload keys on key servers, and fetch certificates over LDAP and WKD.
It encrypts and decrypts files, text and emails, and signs and verifies data. Trust levels and expiry dates can be managed from the same window. It is part of the KDE ecosystem, and a handbook is available on docs.kde.org.
Strengths

- Key lookup through key servers, LDAP and WKD
