Fermat's Theorem Application to Cryptography

Abstract

In this work, cryptography is examined as a means of delivering and storing data in a certain format such that only the intended recipients may read and use it. People have been fascinated for millennia by the possibility of sending messages in a method that is undetectable to enemies. We provide an information-encoding technique that makes use of Fermat's theorem to create a highly impenetrable code. The following theorem's consequence serves as the foundation for the idea. A few elements of public key cryptography applications in number theory. In order to show how encryption and decryption work, this project used an example message.
