Study: Cryptography for information security.

In this paper, a study is based on the cryptography technique for computer science engineering and it is used to transfer readable text into another form that can't be easily understood. Scientifically, it is a technique that involves the study of formulas of mathematics and protecting the information which secures the data. The information can be confidential, authentic, have access control, data integrity, non-repudiation, etc. It is used by mankind to transfer confidential messages without any corruption in the message. Cryptography has changed quickly in little time. Also, this paper discusses the terms used in cryptography, the types of cryptography, and the comparative analysis between them. [ABSTRACT FROM AUTHOR]
