Associated with the process of converting ordinary plain text into unintelligible text and vice-versa. Both the sender and receiver share a single key. The sender uses this key to encrypt plaintext and send the cipher text to the receiver.

Cryptography is a method of protecting information and communications through the use of codes so that only those for whom the information is intended can read and process it. The pre-fix “crypt” means hidden or vault and the suffix “graphy” stands for writing.

Modern cryptography uses sophisticated mathematical equations (algorithms) and secret keys to encrypt and decrypt data.

Today, cryptography is use to provide secrecy and integrity to our data, and both authentication and anonymity to our communications.

Cryptography or cryptology is the practice and study of techniques for secure.
