Symmetric, Asymmetric and Hash Functions

Abstract

The field of cryptography offers numerous methods for transmitting data securely through networks. It usually builds and evaluates several protocols that deal with the numerous facets of information security, such as confidentiality, integrity, etc. Modern cryptography includes a number of engineering and scientific areas. Everyday uses of cryptography include things like computer passwords, ATM cards, and electronic commerce. The term "cryptography" refers to a method of protecting data from unauthorized parties by converting readable and stable information into an unknowable form that can be deciphered on the other end to obtain the needed information using the decoding method supplied by the message's creator. Keywords: Hash function, encryption, symmetric key, and cryptography
