S3QL is a file system that stores all its data online. It supports Amazon S3, Google Storage, and OpenStack and effectively provides you with a hard disk of dynamic, infinite capacity that can be accessed from any computer with Internet access. S3QL provides a standard, full featured Unix file system that is conceptually indistinguishable from any local file system. Additional features include compression, encryption, data de-duplication, immutable trees, and snapshotting, which make it especially suitable for online backup and archiving. The design favors simplicity and elegance over performance and feature-creep. Care has been taken to make the source code as readable and serviceable as possible. Solid error detection, error handling, and extensive automated test cases are provided.
DComSoft SWF Protector makes source code inaccessible for SWF decompilers. It lets you encrypt all ActionScript classes or select the most sensitive ones. It features four reliable protection algorithms, full support for AS 2.0 and AS 3.0, two protection modes (Simple and Advanced), a choice of protection method and its intensity in Advanced mode, batch file protection in Simple mode, and the possibility to get full file information.
CF is a Linux/Unix command line utility for editing/managing AES-encrypted text files. Multiple users can edit the same files using their own separate passwords. It supports basic file locking, piping, adding, changing, removing, and listing keys. Editing sessions are as simple as typing "cf secretfile.cf"; CF asks for a password, decrypts the file, and starts an editor of choice. When the sessions ends, CF picks up the clear text and re-encrypts it. It takes care to let the clear files exist for as short periods of time as possible, and wipes them from memory and disk. It can be used for password management for single users or groups. It can also encrypt/decrypt streams when used in a pipe.
LRZIP is a compression program and library that can achieve very high compression ratios and speed when used with large files using unlimited sized compression windows. It uses the combined compression algorithms of zpaq and lzma for maximum compression, lzo for maximum speed, and the long range redundancy reduction of rzip. It is designed to scale with increases with RAM size, improving compression further. A choice of either size or speed optimizations allows for either better compression than even lzma can provide, or better speed than gzip, but with bzip2 sized compression levels. It also has high grade password protected encryption and full STDIN/STDOUT support.
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.
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.
Attic is a deduplicating backup program. The main goal of attic is to provide an efficient and secure way to back up data. The data deduplication technique used makes Attic suitable for daily backups since only actual changes are stored. Main features: space efficient storage, optional data encryption, and off-site backups.
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.
SaluSafe is an encrypted email, chat, and file storage and sharing system. Your email and files are highly encrypted end-to-end, and cannot be intercepted by any third party. It was built from the ground up for security via strong cryptography, and is not just another security wrapper on top of an existing email solution.
