encryptFS

A simple file system that encrypts each file individually. Designed for use with cloud storage.

Details

High-level overview

1. You have some files abc, 123, asdf.
2. You make an encryptFS in a directory and add all three files. You end up with an encrypted index file and three files with randomly generated names (e.g. e4e90f66761a0ddf52ec47e3d9f1851e3e2304b2b9abd6ae0f818cafa26d56a0).
3. Later, you can open the existing encryptFS and decrypt your files back.

FAQ

• What do you use for the actual encryption? PyCrypto, AES-256 (32-byte key)
• Why are the files encrypted separately instead of being put together in blocks? Isn't this a flaw in the security? For now, I'm willing to trade off the security to simplify the code and to allow for easier/quicker decryption of specific individual files.
• Does this keep my original file metadata? For now, no.

Usage

This project is very new and this API is very subject to change.

Set up

git clone https://github.com/csu/encryptFS.git
cd encryptFS
pip install -r requirements.txt

Example script

from encryptfs import EncryptFS

# Replace `asdfasdf` with a password
encfs = EncryptFS('asdfasdf')

# This will encrypt all new files in the current directory
encfs.encrypt_all()

# This will decrypt all encrypted files in the index
encfs.decrypt_all()
