aCrypt - Python

Ciphering made easy.

Features

• Encode a string into numbers using a secret key
• Decode encoded strings into their original form using a secret key
• Generate a valid aCrypt key

Usage

Examples

Lets say you have private JSON data that you need to encode:

# lets imagine this is the data
data = {
    "username": "ilovecats",
    "password": "meow123"
}

Of course though, writing this un-encoded data can be very unsafe. So the only way to protect it is to cipher it.

from json import dumps, loads
from os import getenv

data = {
    "username": "ilovecats",
    "password": "meow123"
}

# turn the JSON into a string we can encode
data = dumps(data)

# using a key we can store in our environment variables, we can cipher it
encoded_data = cipher(data, os.getenv("CIPHER_KEY")) # you can also keep the key in a variable, thought this is unsafe as users can just use the key

# voila! The data has been ciphered:
print(encoded_data)

And to decipher the data and use it, you can do the reverse:

from json import dumps, loads
from os import getenv

# decipher the data
decoded_data = decipher(encoded_data, os.getenv("CIPHER_KEY"))

# turn the string back into json data
data = loads(decoded_data)

# now you can use it!
print("Your username is" + data.username + "!")
