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.
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.
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.
JBackpack is a personal backup program. It features incremental backups, network transparency, and encryption. JBackpack uses rdiff-backup for all backup and restore functions. SSHFS and SMB are used to access remote file systems. EncFS is used to encrypt backup destination directories.
SQLCipher provides fully transparent encryption of SQLite databases. SQLCipher is a specialized build of the SQLite database that performs transparent and on-the-fly encryption. Using SQLCipher, an application uses the standard SQLite API to manipulate tables using SQL. Behind the scenes, the library silently manages security, making sure that data pages are encrypted and decrypted as they are written to and read from storage. SQLCipher relies on the peer-reviewed OpenSSL library for several encryption requirements, including the AES-256 algorithm, pseudo random number generation, and PBKDF2 key derivation.
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.
