In turn, this key contains the âcypherâ, which dictates how the data encryption occurs. What is a cypher? A cypher is an algorithm for performing encryption and decryption â a series of steps to follow as a procedure. There are many different ways in which plaintext can be encrypted, but essentially there are two main processes used: symmetric key algorithms and asymmetric key algorithms . Algorithms .

The average price of a barrel of crude oil this year is $69.90. Prior to September 11th, 2001, oil cost $23 per barrel.This pricing difference has been attributed to the increasing difficulty to obtain oil from the Middle Eastern region, as well as the increasing shortage of oil supply throughout the world.he average price of a barrel of crude oil this year is $69.90.
