This git project constitutes a file cloaking utility that provides password-based security of a single file or a single file system archive file (E.g. .tar.gz). The utility is probably most useful in the following situations:
- Storing backups of sensitive information on the Internet
- Transporting sensitive information electronically (E.g. email) or manually (E.g. using a flash drive)
This project is already proven running on an Intel/AMD environment (Biostar Celeron CPU motherboard) and the Raspberry Pi 2 (ARM 32-bit processor).
The source code is based on libgcrypt (GnuPG cryptography), using:
- Password-based Key Derivation Function version 2 (PBKDF2)
- AES data cryptography in Cipher-Block Chaining (CBC) mode
- Hash-based Message Authentication Code (HMAC) function SHA512
Reference: https://gnupg.org/documentation/manuals/gcrypt/
Note that you probably already have the run-time libgcrypt shared object library installed. However, to compile the source programs, you will also need the libgcrypt development package (libgcrypt20-dev in the Ubuntu 17.10).
This is NOT commercial software; instead, usage is covered by the GNU General Public License version 3 (2007). In a nutshell, please feel free to use the project and share it as you will but please don't sell it. Thanks!

Subfolders:
- src - C-language source code and a Makefile
- bin - Upon completion of the
makeutility, this folder holds thecloakanduncloakexecutables. - docs - project documentation (admittedly, skimpy)
- data - project example data files
The starting point with this project is in the docs/operations.txt file. Also, this note contains for cloaking the sample cleartext data and uncloaking the ciphertext.
