choppy
=======
chop -> encrypt -> (?) -> decrypt -> merge

Choppy partitions files and encrypts using symmetric authenticated cryptography.
After decryption, embedded metadata provides for the original input file to be recreated and verified.

- selectable number of partitions and randomized file size
- secure cryptographic key/password input or via file
- sequential numeric or randomized file names
- encrypted file chunks can have name and extension altered with no detriment to recreating input file
- chunks from multiple files can be located within the same directory and the merge command will locate and reassemble original input files


Installation
------------

Using pip:

::

    pip install choppy

Without pip - clone repository:

::

    python setup.py install


Command Line Usage
------------------

See
`Usage <https://github.com/j4c0bs/choppy/blob/master/docs/usage.md>`_
for advanced use and expanded options.


generate cryptographic key file (key.txt)

::

    choppy gen -k

create 10 partitions of infile.txt, randomize partition size by 50% and encrypt with key file

::

    choppy chop infile.txt -n 10 -w 50 --use-key -i key.txt

decrypt partitions and merge to reassemble original file

::

    choppy merge *.chp.* --use-key -i key.txt


Requirements
------------

- Python 3.6 or greater
- cryptography 2.1.3
