Easy Crypt

Data encryption with RSA key pair.

If you need to store some confidential text — this package will keep your data safely encrypted. No more leaks!

This project is built on top of PyCryptodome and aim to provide an easy and accessible interface.

1. The RSA public key is used to encrypt the session key;
2. The AES session key is used to encrypt the data.

Installation

Requirements

• Python;

In BSD Unix or GNU/Linux distributions you can easily generate a key pair using OpenSSH:

ssh-keygen -t rsa
ssh-keygen -y -f eccrypt_rsa > eccrypt_rsa.pub  # if you have a private one

In Windows you can also generate a key pair using PuTTY:

• Open PuTTYgen;
• Click the Generate button and move the mouse over the blank area;
• Copy your public key from the text area and paste it in a new file (ex. eccrypt_rsa.pub);
• Open the Conversions submenu and select Export OpenSSH key;
• Save your pivate key (ex. eccrypt_rsa);
• Close PuTTYgen and keep your private key secret.

Since v0.0.4 it is possible to generate a key pair directly from the menu bar: File > Generate key pair.

Installation

Clone the repository, change the current directory and install the dependencies:

git clone https://github.com/i5ar/eccrypt.git
cd eccrypt
python setup.py install

If something goes wrong try to update the package manager:

python -m pip install --update pip
pip install -r requirements.txt

Quickstart

Graphical interface

Since v0.0.2 it is available a simple graphical interface.

You still need to launch it from the terminal.

For the time being, just run python main.py.

Terminal

Encrypt a file:

eccrypt encrypt data/egg.txt --public-key eccrypt_rsa.pub

Decrypt a file:

eccrypt decrypt data/egg.bin --private-key eccrypt_rsa

Note

Original EOL might not be restored depending on your operating system.

Development

Generate some dummy text in the data directory:

node loremipsum.js

Create a source distribution:

python setup.py sdist

create built distributions:

python setup.py bdist_wininst  # Windows
python setup.py bdist_rpm  # RPM-based system

Documentation

Add new docstrings to the API documentation:

make clean -C ./docs  # remove previous build
sphinx-apidoc -o docs eccrypt -f  # force override
make html -C ./docs  # build

Changelog

• v0.0.6 - Add command line script;
• v0.0.5 - Add documentation;
• v0.0.4 - Add generate module (RSA key pair);
• v0.0.3 - Improve the graphical interface;
• v0.0.2 - Add a simple graphical interface.

TODO

• Try out loremipsum and eventually integrate for testing purposes;
• Store the key pair in a database;
• Apparently, I need to come up with a hook for the installer.
