About MultiCrypter

MultiCrypter consists of two Python scripts (MultiCrypt.py and MultiDecrypt.py) that allow you to encrypt and decrypt a python file using multiple passwords. The decrypt works with any of these passwords and extract, run the file in the memory, marked with the entered password. It uses the following libraries and modules:

  • cryptography for cryptographic primitives:
    • Fernet for symmetric encryption/decryption
    • PBKDF2HMAC for deriving keys from passwords
  • base64 for encoding binary data
  • os for generating random salts
  • hashes from the cryptography.hazmat.primitives package
  • default_backend to specify the cryptographic backend

How It Works

  1. Encryption (CryptMulti.py)

    • Prompts you for a file path to the source code you want to encrypt.
    • Uses three different passwords (e.g., 12345A, 12345B, 12345C - you can choose them by yourself) to encrypt the code in segments.
    • Saves the combined encrypted data as encrypted_code.bin.

  2. Decryption (DecryptMulti.py)

    • Reads the encrypted_code.bin file.
    • Asks for a password.
    • Attempts to decrypt each segment in turn using the provided password:
      • If decryption is successful, it prints and optionally writes the decrypted code to extract.py.
      • Executes the decrypted code via exec().
      • If no segment can be decrypted with the given password, it prints an error message.

Getting Started

  1. Clone the repository: 
    git clone https://github.com/xchimx/Python-MultiCrypter
cd Python-MultiCrypter
pip install -r requirements.txt
py ./MultiCrypt.py to crypt the python file (try the HelloWorld.py example in Testfile subdir
py ./MultiDecrypt.py to decrypt the python file with one of the passwords
