CryptographyKit 1.0.0

This package is intended to provided users with a quick and simple ways to perform a one time pad encryption, ceaser cipher, or vigenere cipher. It will work with python 2 or 3.

This kit is intended to provided users with a quick and simple forms of encrypts. Some modules like
HideMessageInImage and CaesarCipher, while not very strong forms of encryption are provided for the
sake of having them easily available.

USAGE:
External Modules Required
-------------------------------------------------
-------------------------------------------------
pyminizip, and PIL
All these modules can be installed via the pip command

[pip install pyminizip] or [pip3 install pyminizip]
[pip install Pillow] or [pip3 install Pillow]
[pip install easygui] or [pip3 install easygui]


Import Modules
-------------------------------------------------
-------------------------------------------------
from Cryptokit.OneTimePadEncryption import encrypt_data, decrypt_data
from Cryptokit.CaesarCipher import c_encipher, c_decipher, brute_force_decrypt

from Cryptokit.HideMessageInImage import hide_or_show_message


Description of Methods:
-------------------------------------------------
-------------------------------------------------

Module --> OneTimePadEncryption
-------------------------------

encrypt_data(plain_text, string_file_mode=False) --> Takes plain text as either a string
or a text document and returns a key file and encrypted message file. Date times are used to match
the key file with the encrypted message file.

decrypt_data(key, encrypted_string, key_file_mode=False, string_file_mode=False)
--> Takes a key and an enencrypted message as either a text document or a file. It will return the
plain text document assuming the right key is supplied.

Module --> CaesarCipher
-------------------------------

c_encipher(plain_text, key, plain_text_file_mode=False) --> Plain text is shifted up by the key
provided. The key must be in the range of 1-26.

c_decipher(cypher_text, key, cypher_text_file_mode=False) --> Cipher text is shifted by the key
provided. The key must be in range of 1-26. The key must be the same key used to encipher other
wise garbage data will be returned.

brute_force_decrypt(cypher_text, cypher_text_file_mode=False) --> This will attempt to return the
key used and the plain text translation of the enciphered text.

Module --> VigenereCipher
-------------------------------

v_encipher(plain_text, key, file_mode=False) --> Plain text is enciphered using the given key
provided key. The key that is provided must be in a string containing only English characters.

v_decipher(cipher_text, key, file_mode=False) --> Cipher text is deciphered using the key that was
used to encipher the message. The key that is provided must be in a string containing only English
characters.

v_dictionaryattack(cipher_text, dictionary_file="helper_files/dictionary.txt", file_mode=False,
percent_match=55) --> Function that takes cipher text either as a string or as a text file and trys
and returns the plain text message. Things to note; the dictionary_file argument is passed a default
dictionary, which is used to try and crack the cipher text. The percent_match arugument is used to
specify how close the deciphered message has to be to English, see the detectEnglish module located
in the helper_files folder for more information.


Module --> HideMessageInImage
-------------------------------

hide_or_show_message() --> This will prompt the user to type in a message. It will return a png file with
your message hidden inside. Run the function again to if you want to decrypt a png file.
