Bread

Bread is a multithreaded encryption daemon that monitors the specified directory for files that are moved into it. Upon detecting a new file, the daemon encrypts the file using OpenPGP standard, in case a directory is moved into monitored directory, the daemon encrypts the files present inside the directory recursively. Note: The daemon only processes files that are moved into the directory, not those that are copied.

The logs can be found in bread.log file in monitored directory.

Features:

• Secure decryption key: Files are encrypted using a public key, ensuring that the decryption key remains protected and secure.
• Cryptographically secure encryption: The daemon uses the GPGME library, which provides a high-level interface to GnuPG, ensuring that the encryption is cryptographically secure.
• High performance: The daemon is multithreaded, ensuring high-speed processing and efficient handling of multiple file encryption tasks simultaneously.

Getting started:

Installing gpgme:

On debian:

sudo apt install libgpgme-dev

On arch:

sudo pacman -S gpgme

Building project:

git clone https://github.com/de-ep/bread.git
cd bread 
make 

Usage

./bread ~/protected_dir ABCD1234

• ~/protected_dir: The directory to monitor for moved files.
• ABCD1234: The fingerprint (or key ID) associated with the public key for encryption.
