Fast File Encryption
======================
The *Fast File Encryption* is an open, very simple and well-designed file encryption solution for medium and large files (up to terabytes). It uses asymmetric RSA keys to encrypt and decrypt the files, in order to store the public key for encryption on the server, with no worries.
Quick Usage Overview
--------------------
Create a new key pair:
.. code-block:: pycon
>>> import fast_file_encryption as ffe
>>> from pathlib import Path
>>> ffe.save_key_pair(public_key=Path('public.pem'), private_key=Path('private.pem'))
Encrypt a file:
.. code-block:: pycon
>>> original_file = Path('original_file.txt')
>>> original_file.write_text('Hello world!')
>>> encryptor = ffe.Encryptor(ffe.read_public_key(Path('public.pem')))
>>> encrypted_file = Path('encrypted_file.ffe')
>>> encryptor.copy_encrypted(original_file, encrypted_file, meta={'my-meta': 1}, add_source_metadata=True)
Decrypt a file and read its meta data:
.. code-block:: pycon
>>> decryptor = ffe.Decryptor(ffe.read_private_key(Path('private.pem')))
>>> decryptor.load_decrypted(encrypted_file)
b'Hello world!'
>>> decryptor.read_metadata(encrypted_file)
{'my-meta': 1, 'file_path': '.../original_file.txt', ...}
Installation
------------
Install *Fast File Encryption* using ``pip``:
.. code-block:: console
$ pip install fast_file_encryption
