AES 256 Encryption and Decryption

A beginner-friendly console project demonstrating AES-256 encryption and decryption in Python. It uses AES in GCM mode (authenticated encryption) with a key derived from your password via scrypt.

Choose 1 to encrypt a message (prints the cipher text, salt, nonce and tag) or 2 to decrypt by entering those values back.

How to run

pip install pycryptodomex
python AES256.py

Dependencies

• pycryptodomex — the Cryptodome AES implementation

Pyodide-runnable

Yes. pycryptodome is available in the Pyodide playground, and the program is a pure input()/print() console app. The screen-clearing os.system call was removed so it runs cleanly in-browser.
