Secure File Manager

C++ application for secure file encryption, decryption, hashing, and digital signature management. This project leverages OpenSSL for cryptographic operations and a command-line interface.

Features

• File Encryption: Encrypt files using AES-256-CBC for secure storage and transmission.
• File Decryption: Decrypt encrypted files to retrieve original content.
• File Hashing: Generate SHA-256 hashes for verifying file integrity.
• Digital Signatures: Sign files with a private key and verify signatures with a public key.
