JUC is a simple Unicode based text crypter

Update: I did this program when I was still not very experienced on computer security ( even now I’m not an expert ) , it was created only as a leisure and I do not recommend using it for projects where you need serious security system.

File Encrypter

Original and decrypted file differences

The quality of the original file and the decrypted file is equal :)

Text Crypter

Examples

Encrypting a text

from JUC import *
worker = Juc('YourSecretKey')
print(worker.crypt(b'ehy, hello there'))

Decrypting a text

from JUC import *
worker = Juc('YourSecretKey')
print(worker.decrypt(text).decode())

Encrypting a file

from JUC import *

worker = Juc('YourSecretKey')

filePath = 'image.png'

with open(f'result.png', 'wb') as f:
    with open(filePath, 'rb') as file:
        content = file.read()
        crypted = worker.crypt(content)
        f.write(crypted.encode())

Decrypting a file

from JUC import *

worker = Juc('YourSecretKey')

filePath = 'result.png'
fileType = filePath.split('.')[-1]

with open(filePath, 'r') as file:
    content = file.read()
    with open(f'result-decrypted.{fileType}', 'wb') as f:
        decrypted = worker.decrypt(content, False)
        f.write(decrypted)
