• There are several forms of public key encryption, including:
  • Public key encryption.
    • Keeping a message secret from anyone that does not possess a specific private key.
      • RSA encryption is a widely used algorithm which uses prime factorization.
  • Public key with a digital signature.
    • Allowing anyone to verify that a message was created with a specific private key.
