Public Key Cryptography Includes:
- A public key that encrypts data to ensure confidentiality, and a private key for decryption. A message encrypted with a recipient's public key is decrypted by the recipient possessing the corresponding private key.
- Digital signatures to ensure authenticity. A message signed with a sender's private key can be verified by the sender's public key, thereby proving that the sender signed it and that the message has not been tampered with.
