UsbCryptFormat is a graphical user interface (GUI) for the encryption of USB flash drives or external hard drives. It allows the user to reformat a USB flash drive, an SD card, or an external hard drive with an encrypted filesystem very easily and without the danger of destroying data on an internal hard drive because of incautious handling of device names. So it is usable even for a layperson.
Privatix Live-System is a portable encrypted operating system designed to be run directly from a USB flash drive or an external hard drive. This allows the user to safely edit and carry along sensitive data for encrypted communication and anonymous Web surfing. It is based on Debian GNU/Linux.
losetup-utils are three bash scripts that attempt to make the use of losetup a bit easier and faster. losetup can be fast, easy, and practical if you need to transport sensitive information over the Internet or in CD's, DVD's, or a pendrive. Also, if you want to store private data on your hard disk or in the cloud, an encrypted volume can be a convenient choice. The types of encryption can be any installed on the system.
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.
eacc is a bash script that allows a group of people to share an encrypted, revision controlled file on a shared filesystem. Rather than store an encrypted file in RCS, eacc encrypts the RCS file and handles the decryption, check-out, check-in, and encryption steps automatically. The repository is encrypted using GPG's multi-recipient support, which allows each member of the group to use their own unique password. A typical use case would be to securely store sensitive information, such as password lists or account information, that is shared by a team.
