This project is an implementation of the Pretty Good Privacy (PGP) protocol in Python, offering various types of encryption, key management, and secure message transmission between multiple users. PGP is used for securing communications by providing confidentiality, integrity, and authentication.

• Encryption Algorithms: Supports multiple encryption schemes such as:
  • Symmetric encryption (AES, DES, etc.)
  • Asymmetric encryption (RSA)
• Key Management:
  • Key generation (public and private keys)
  • Secure key storage and retrieval
• Message Signing: Digital signatures to ensure message integrity.
• Message Encryption: Encrypt and decrypt messages between multiple users using PGP.
• User Authentication: Ensure that messages are sent from verified users.
• Compression: Optionally compress messages before encryption to save bandwidth.
• Integrity Checking: Provides mechanisms to ensure that messages have not been tampered with.
