This project showcases secure communication using a custom SSL/TLS protocol to protect interactions between clients and the server. Public-key certificates are used for identity verification, and RSA encryption ensures message security.

Key Components:

SecureServer: Manages SSL/TLS connections with clients. Verifies client certificates and handles encrypted messages. Maintains client lists and manages secure groups for message encryption.

SecureClient: Encrypts messages with the server's public key and handles communication securely. Manages RSA key pairs and X.509 certificates for secure messaging.

Cryptographic Utilities (UtilsCrypto): Provides methods for encryption, decryption, signature creation, and verification. Key pair and self-signed certificate generation.

Features: SSL/TLS for secure communication. Public-key encryption (RSA) with X.509 certificates. Client and server authentication. Secure message exchange with digital signatures.

Future Improvements: Implement certificate authority (CA) for robust certificate management. Add forward secrecy for enhanced security in sessions. Extend functionality for secure file transfers or email communication.
