- observe "deterministic" and "probabilistic" encryption respectively
in the demo

- 3DES demo using key ring option#2
- password to key/IV using PBKDF
- what is a salt? why it is used with password
- seeing the encrypted output using base64 encoding
- binary vs base64 encoding
- how base64 encoding works
