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.
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.
TruPax is a tool for creating TrueCrypt volumes directly from files and folders. Volume sizes are precisely adjusted to the actual amount of data, so there is no slack. They mount on any modern OS and are of UDF 1.02 format. Creation happens quickly and directly, by creating the file system structures in the encrypted container on-the-fly. TruPax does not require TrueCrypt to be installed nor administrative rights. GUI and command line versions are available. The original material can be securely erased after a volume has been created. Volumes created by TruPax can also be extracted and all TrueCrypt volumes can be quickly invalidated.
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.
Lessfs is a high performance inline data deduplicating file system for Linux. Lessfs complies to the POSIX standard and is very useful for backup purposes as well as providing storage for virtual machine images. Although lessfs is a file system that is implemented in user space with FUSE, it offers decent performance. Lessfs is capable of handling data rates up to 350MB/sec. It supports filesystem encryption.
QPass is a password manager application. It enables you to store your confidential data encrypted. All entries are stored in a single-file database encrypted using the AES-256 algorithm. Each entry can contain a name, URL, username, password, and description. QPass can also generate random passwords based on mouse movements.
