Security plays a full of danger position in keeping safe news given right not to be public and secrecy. Many process of changing knowledge into a secret form carefully worked designs are ready (to be used) to keep safe facts during sending (power and so on) or place for storing. These process of changing knowledge into a secret form methods (make, become, be) different in terms of power, speed, and useable materials using up (cpu 1 use, memory, and power). This learning process try to present the most having general approval and interesting algorithms currently in use.
