AES Encryption Tool - Secure File Encryption and Decryption

This pull request introduces a robust AES encryption tool for securely encrypting and decrypting files using AES-CBC mode. The tool leverages password-based key derivation (PBKDF2 with HMAC-SHA256), ensuring strong encryption for sensitive data. It automatically handles key derivation, file padding, and secure random generation of salts and IVs.

Key Features:

• Simple command-line interface for encryption and decryption.
• Automatic output file naming and padding for non-aligned data sizes.
• Secure key derivation from user-provided passwords.
• Clear error handling for incorrect decryption attempts.
