Kleopatra Neo is a modern, privacy-first encryption app for everyone. Encrypt and decrypt messages and files with OpenPGP, sign and verify signatures, and manage your PGP keys, X.509 / S-MIME certificates and passwords, all from one clean, fast app. Everything happens on your device. Your private keys and passwords are encrypted with AES-256 before anything is ever synced, so our servers only ever store ciphertext. This is zero-knowledge by design: neither we nor anyone else can read your data. What you can do: - Encrypt and decrypt PGP messages and files - Sign messages and verify signatures automatically against your keys - Generate and import OpenPGP keys (RSA and ECC) - Manage X.509 / S-MIME certificates and create self-signed certificates - Store logins in a built-in password manager with a strong password generator - Keep a local history of what you encrypted and decrypted, and restore it in one click - Optionally sync your encrypted vault across your devices Basic encryption and decryption are always free and fully local, and the app works offline. Kleopatra Neo offers optional in-app purchases: a paid subscription, bought on our website outside the Microsoft Store, unlocks syncing across more than one device. Kleopatra Neo is the friendly companion to GnuPG and the classic Kleopatra key manager, rebuilt for a smooth desktop experience.
