DEFFS
A custom FUSE-based filesystem that distributes encrypted shards of data across machines on a local network, allowing those files to be accessible from any machine.

Build
cmake .
mkdir bin
cmake --build ./ --target DEFFS -- -j 6
- Mount
mkdir ~/deffs_mountpoint
mkdir ~/deffs_storepoint
./bin/DEFFS ~/deffs_mountpoint ~/deffs_storepoint
# DEFFS now mounted at ~/deffs_mountpoint
# Files are interacted with within the mountpoint, but are stored at the storepoint
# It is not advised to modify any files in your storepoint
Usage
Right now, DEFFS can be used like a typical EXT4 filesystem. It will store encrypted data shards in
This filesystem's encryption is based on the AES_encrypt method, meaning:
- It is NOT (yet) resistant to attackers
- Making files with unencrypted content longer than 15 characters is undefined (soon to be fixed)
Currently, DEFFS only encrypts files when the write syscall is called. Soon, write_buf will be supported as well. Files are decrypted upon read.
Proper usage of DEFFS looks like this:
test/helloworld.txt
cat test/helloworld.txt
">
cd mountpoint mkdir test touch hello echo "hello world" > test/helloworld.txt cat test/helloworld.txt
