Encrypt and decrypt texts on a secure way using maps

📂 Mapify

Encrypt and decrypt texts on a secure way using maps.

Mapiwhat?

Mapify is a small python package made for easy encrypting texts. It can be used to save data on a secure way.

There are currently 3 functions available, which you can use:

• Encrypt
• Decrypt
• Generate

How to get it?

By simply installing the package using pip install mapify are all files imported and ready to use.

How to use it?

Like every python package is an easy import all you need. An example below:

# Importing the package
import mapify


# Main code
text = "Hello world!"
print(f"Original text: {text}")

# Generate a random map, based off the standard default.toml file with seed 500 to reuse it later on. A "map.json" file will be generated.
mapify.generate(map_name='map', map_type='json', seed=500)

# We encrypt the text variable and use the newly generated map "map.json".
encrypted_text = mapify.encrypt(input_text=text, used_map="map.json")
print(f"Encrypted text: {encrypted_text}")

# We decrypt the encrypted text with the same map we used to encrypt it
decrypted_text = mapify.decrypt(input_text=encrypted_text, used_map="map.json")
print(f"Decrypted text: {decrypted_text}")

output:

Original text: Hello world!
Encrypted text: 94 142 161 82 200 16 82 198 46 45 182
Decrypted text: Hello world!

Module: Generate

The generate module isn't necessary when using this package. It only exists to generate your own/new random map to, use based off an existing map.

This module only randomizes the already existing values. All parameters explained below:

from mapify import generate

generate (
    map_name = "map-2",
    map_type = "json",
    seed = None,
    original_map = "map-1.toml",
    special_words = ["name", "I like python", "username", "password"]
)

• Map name - The name of the new generated map. If none given, then the program won't make a file.
• Map type - The type of file you prefer the map must be. Only json or toml is supported.
• Seed - The seed on which the map must be randomized. This can be used as actual key instead of a map file.
• Original map - The map where the new map must be based off. If none given, the standard default.toml will be used. This file is listed below.
• Special words - The words which need their own key in the new map. This way, is it easy to keep some words completely safe.

Return value - When executing this module, the full name of the new map format will be returned (E.g. "map.json"). You can catch it with a variable to use it when you're encrypting or decrypting.

Module: Encrypt

The encrypt module is the main module when using this package. It transforms the input text into cipher text using the attached map.

All parameters explained below:

from mapify import encrypt

encrypt (
    input_text = "I love Python!",
    used_map = None,
    strip_input=False
)

• Input text - The text which has to be encrypted.
• Used map - The map file which the program has to use to encrypt. If none given, the default.toml file will be used.
• Strip input - When reading different lines, there might be a \n on the end of an input string. When True, the program will filter it out.

Return value - When executing this module, the encrypted text in string format will be returned. You can catch it with a variable to use it in your own program.

Module: Decrypt

The decrypt module is the second main module when using this package. It transforms cipher text back into readable text using the attached map.

All parameters explained below:

from mapify import decrypt

decrypt (
    input_text = "51 34 29 17 24 23",
    used_map = None
)

• Input text - The text which has to be decrypted.
• Used map - The map file which the program has to use to decrypt. If none given, the default.toml file will be used.

Return value - When executing this module, the decrypted text in string format will be returned. You can catch it with a variable to use it in your own program.

What are map files?

Map files are json/toml files which can be made or generated (copied + randomized) with the generate module. An example below:

[map]
    1 = "I"
    2 = "Love"
    3 = "Python"

The text "I love python" would become "1 2 3" in cipher text

You don't have to stay at 1 character, like the default.toml file is build from. The program checks until it can find a reference. This means that you can even save this, which would encrypt "I love python" into "1 2"

[map]
    1 = "I lo"
    2 = "ve python"

You can already see why this can be safe. As long as the map file and/or seed when generating isn't exposed, is your text completely safe! Like your own password.

Challenge

Still not convinced that it's safe? Try to crack this ciphertext!

main.py:

# Imports
from mapify import encrypt, generate


# Setting variables
secrets = ["name"]
map_used = generate(map_name="map", special_words=secrets)

# Encrypting line per line
with open("famous-poem.txt") as poem:
    for line in poem:
        encrypted_line = encrypt(line, map_used)
        print(encrypted_line)
