Ever since Netscape Communications invented the Secure Sockets Layer Protocol (SSL) in 1994, after the Internet becomes under scrutiny over security, the arms race between code breakers and code makers has been accelerated in the field of the internet cryptography.

From Wikipedia. Autotroph. An autotroph, also called a producer, is an organism that produces complex organic compound s (such as carbohydrate s, fat s, and protein s) from simple inorganic molecules using energy from light (by photosynthesis) or inorganic chemical reactions (chemosynthesis).hus, heterotrophs animals, fungi, as well as most bacteria and protozoa depend on autotrophs for both energy and raw materials to make complex organic molecules. This mechanism is called primary production in the sea. Heterotrophs obtain energy by breaking down organic molecules obtained in food.
