This repo is a simple helper to encrypt / decrypt files. It entirely relies on the cryptography package: don't hesitate to read how they addresse security issues in this article

Create a virtual environment with python 3.9, for example with conda:

conda create -n encr_env python=3.9

Install the package in your virtual environment:

conda activate encr_env
pip install git+https://github.com/EtWnn/FileEncryptor

To encrypt a file, execute the command:

conda activate encr_env
file_encryptor encrypt <path/to/file>

The encrypted file will be written at <path/to/encrypted_file

To decrypt a file execute the command:

conda activate encr_env
file_encryptor decrypt <path/to/file>

The decrypted file will be written at <path/to/decrypted_file

For every encryption or decryption, you will be prompted a password and a salt.

The password is non-case sensitive, accents will be converted and punctuation will be removed. The salt is a number used in encryption key generation process.

To achieve a successful decryption, both password and salt must be identical to the ones used when encrypting a file.
