# PyMangler for Python 3
PyMangler contains a pure-python3 "encryption" scheme
that can be used to *obfuscate* and *disguise* data
in situations where strong encryption is not available,
and security is not necessarily top priority. It is
fairly fast but large amounts of data takes time.
Files can be encrypted if the file data is encoded to
base64 before encrypting but it's too slow to be useful.
This was written as a "proof of concept" because I
was wondering if I could come up with an encryption
scheme that
A.) Didn't produce repeating patterns
B.) Could withstand a frequency analysis attack
### Install
pip3 install PyMangler
### Setup
The key file that comes with PyMangler will work,
but you should generate a new key by running the
`keygen.py` file. You should see the following
text and a file named `key` will be generated:
Generating key...
Key generated.
Validating key for prosperity...
Key is valid. Encryptor working successfully!
Key validation from the built in key generator
should realistically never fail, but it's validated
anyway.
PyMangler's encryption algorithm was designed to give
a fairly flat distribution frequency, and repeating
patterns in pre-encrypted text does not generate
repeating patterns in the cipher-text unless you
were to repeat the same characters an abnormal amount
of times in the pre-encrypted text.

### Usage
```python
from PyMangler.mangle import Encryptor
# The Encryptor class will generate a key to use
# on instantiation. Save your key file or else
# you won't be able to recover encrypted data.
e = Encryptor()
e.save_key_file(filepath='/Path/To/Key/File')
# once you save a key file you wouldn't want to
# overwrite it so make sure you create a key
# generator or use the one provided.
# You can load the key file you saved.
e.load_key_file(filepath='/Path/To/Key/File')
# If you don't like PyManglers key contruction
# methods you can use the make_key method to
# create your own. Just pass a list of random
# characters and Encryptor will number each
# character starting from 1.
e.make_key(['d', 'c', 'b', 'e', 'g', 'a', 'f'])
# if you want Encryptor to randomize your
# key for you, use make_randomized_key.
e.make_randomized_key(['a', 'b', 'c', 'd', 'e', 'f', 'g'])
# Using either make_key or make_randomized_key
# will make Encryptor use your given characters
# Calling Encryptor.save_key_file will save your
# created key to a file that can be loaded later.
```
