DAR - Disk ARchive
For full, incremental, compressed and encrypted backups or archives
DAR is a command-line backup and archiving tool that uses selective compression (not compressing already compressed files), strong encryption, may split an archive in different files of given size and provides on-fly hashing, supports differential backup with or without binary delta, ftp and sftp protocols to remote cloud storage Archive internal's catalog, allows very quick restoration even a single file from a huge, eventually sliced, compressed, encrypted archive eventually located on a remote cloud storage, by only reading/fetching the necessary data to perform the operation. Dar saves *all* UNIX inode types, takes care of hard links, sparse files as well as Extended Attributes (MacOS X file forks, Linux ACL, SELinux tags, user attributes) and some Filesystem Specific Attributes (Linux ext2/3/4, Mac OS X HFS+) more details at: http://dar.linux.free.fr/doc/Features.html -

FreeOTFE
A free "on-the-fly" transparent disk encryption program for PC & PDAs.
An upstream source site housing the original files for this mirror is no longer available. With this software, you can create one or more "virtual disks" on your PC/PDA. These disks operate exactly like a normal disk, with the exception that anything written to one of them is transparently, and securely, encrypted before being stored on your computer's hard drive. -

Picocrypt NG
A very small, very simple, yet very secure encryption tool
Picocrypt NG is a free, open-source file encryption utility that continues development of the original Picocrypt project. It protects individual files and folders using authenticated encryption and password-based key derivation. Users can secure information with passwords, keyfiles, or both. Its PCV3 format provides modern encryption while retaining support for reading older Picocrypt volumes. Optional Paranoid Mode adds another encryption layer for additional protection. Reed-Solomon error correction helps recover data affected by limited file corruption. The application includes a password generator, encrypted archives, and recovery tools. It provides desktop, command-line, Android, and browser-based interfaces with platform-specific capabilities. -

BIP39-XOR
Encrypt or decrypt 12, 15, 18, 21 or 24 BIP39 codewords array ("seed")
Encrypt or decrypt 12, 15, 18, 21 or 24 BIP39 codewords array (so-called "seed phrase") using exclusive OR (XOR)/Vernam cipher (a.k.a. One Time Pad). If not input by a user, an encryption key is automatically generated at random. Encryption with such a key preserves integrity of BIP-39 checksums of all keys (that's distinct while also compatible with SeedXOR implementation). -
