WebCryptography is a term used in computer science to describe secure information and communication techniques that transform messages in difficult-to-decipher ways using mathematical concepts and a set of rule-based calculations known as algorithms. WebIn cryptology, the discipline concerned with the study of cryptographic algorithms, a cipher is an algorithm for encrypting and decrypting data. Symmetric key encryption, also called secret key encryption, depends on the use of ciphers, which operate symmetrically.

WebSymmetric encryption is a method of encryption where electronic communication is twain encrypted and decrypted using just one key (a hidden key). The key must be shared between individuals communicating through symmetric encryption so that it can be utilised in the procedure of decryption. WebCryptography uses mathematical techniques to transform data and prevent it from being read or tampered with by unauthorized parties. That enables exchanging secure messages even in the presence of adversaries. Cryptography is a continually evolving field that drives research and innovation.

Webcryptography (krĭptŏgˈrəfē) [Gr.,=hidden writing], science of secret writing. There are many devices by which a message can be concealed from the casual reader, e.g., invisible writing, but the term cryptography strictly applies to translating messages into cipher or code. The science of breaking codes and ciphers without a key is called ...
