The Horcrux project

This tool allows you to securely store your data by encrypting the content and splitting it into several files.

Usage

To encrypt a file use the following syntax:

horcrux create -n <horcrux count> <input path> <output path>

• -n <horcrux count>: number of files the encrypted data will be split into.
• <input path>: file to encrypt.
• <output path>: folder where to save the encrypted files.

To decrypt a file use the following syntax:

horcrux load -k <decryption key> <input files> <output file>

• -k <decryption key>: provide the encryption key, base64 encoded.
• <input files>: horcrux chunks to be reassembled. Order matters :)
• <output file>: decrypted data.

Compile

This tool is compiled using Cmake and it has been tested with gcc-10 on linux.

Use the following commands to compile the tool:

mkdir build && cd build
cmake ..
make

Dependencies

horcrux needs OpenSSL-1.1 or a newer version.

Test

You can run make test from the build directory, or use test/horcrux_test for a more verbose output.

Install
