While there are many different security methods, most use a secret key to protect the results and then a procedure for transformation or substitution to conceal its original style. The producing cipher text may possibly appear because confusing heroes and emblems to an not authorized party, called plain text.

Aside from protecting privacy, encryption provides authenticity and integrity to demonstrate that the fundamental information or communications is actually not changed from the original state.
