Dual Key Encryption

• Also Known as Public key or Asymmetric encryption

  • A unique key pair is generated one public and one private
  • Secret Key cannot be derived from public

• Public Key Encryption

  • Sender uses your public Key to send you an encrypted message
  • You decode the message with your secret key never having to reveal it to anyone

• Private Key Encryption

  • Your message is encrypted with your private key
  • Anyone who has your public key can decrypt this message

• Digital Signature

  • When your communication is not sensitive enough to warrant encryption
  • Using the secret key and a hash of the original message a signature block is created
  • The recipient can use your public key to validate not only that you originated the message but that it was also not modified in transit
