Dictionary definition: the art of writing or solving codes.

'Crypto' (Hidden) 'Graphia' (Writing)

Cryptography is but a tool to maintain security. See also Kerckhoffs’ principle

Through cryptography we can maintain PAIN:

  • Privacy
  • Authenticity
  • Integrity
  • Non-repudiation

With cryptography we can secure an already secure process in an insecure environment. It's not possible to secure an insecure process.
