File Encryptor

A Python script to encrypt and decrypt files using AES encryption with a password-derived key.

Features

• Encrypt a text file using an auto-generated password and AES-256-CBC.
• Decrypt the file with a password prompt.
• Uses SHA-512 for key derivation with PBKDF2.

Requirements

• Python 3.x
• cryptography library

Install Dependencies

To install the required dependencies, use the following command:

pip install cryptography

Usage

Encrypt a File

To encrypt a file (file.txt), use the following command:

python crypter.py -e file.txt

This command will output an encrypted file named file.txt.enc and display the generated password on the screen.

Decrypt a File

To decrypt a file (file.txt.enc), use:

python crypter.py -e file.txt

• This command generates an encrypted version of file.txt named file.txt.enc.
• An auto-generated password will be displayed on the screen for decryption purposes.

Decrypt a File

To decrypt a file (file.txt.enc):

python crypter.py -d file.txt.enc

• The program will prompt for the previously generated password.
• Once verified, it will produce a decrypted version of the file named file_decrypted.txt.
