Making a case for `ChaCha20-Poly1305` ?? #24

The aim is to let user choose from the pool of competent encryption algorithm that best suits their need:

AES256 in Cipher Block Chaining mode - [ currently available ]
ChaCha20 ( with 192-bit nonces and message authentication using Poly1305 )
- doesn't require hardware acceleration
- not vulnerable to cache-timing attacks
- RFC, Dart Implementation

ChaCha20 is relatively faster compared to AES on older devices, but most modern mobile-phone processors supports AES-NI thus making AES also faster.

Cool idea
