Cryptography, [1] or cryptology, is the practice and study of hiding information. It is sometimes called code, but this is not really a correct name. It is the science used to try to keep information secret and safe. Modern cryptography is a mix of mathematics, computer science, and electrical engineering.
Cryptography, or cryptology (from Ancient Greek: κρυπτός, romanized : kryptós "hidden, secret"; and γράφειν graphein, "to write", or -λογία -logia, "study", respectively [1] ), is the practice and study of techniques for secure communication in the presence of adversarial behavior. [2]
RSA algorithm. RSA (Rivest–Shamir–Adleman) is an algorithm used by modern computers to encrypt and decrypt messages. It is an asymmetric cryptographic algorithm. Asymmetric means that there are two different keys. This is also called public key cryptography, because one of the keys can be given to anyone.

A cypher is an algorithm for performing encryption (coding) or decryption (decoding). It is a series of well-defined steps that can be followed as a procedure. To encipher or encode is to convert information from plain text into cipher or code.
In cryptography, a key (or cryptographic key) is a piece of information that allows control over the encryption or decryption process. There are two basic types of cryptographic algorithms . Symmetric algorithm: If there is just one key for encrypting and decrypting, the algorithm is called symmetric. Asymmetric algorithm: If there are two ...
