CryptBackup is an encrypted backup application for Linux desktop users. It allows even a layperson to backup their home directory (including the desktop) on an encrypted external device with just a few clicks. Even the setup is only to choose the external device (such as an external hard drive) and to set a password.
GoAnywhere OpenPGP Studio is a desktop tool that allows you to protect sensitive files using the Open PGP encryption standard. Documents can be encrypted, decrypted, signed, and verified from your PC or workstation. An integrated key manager allows you to create, import, export, and manage Open PGP keys needed to encrypt and decrypt files.
