WebCryptography, in a broader sense, is the process of creating and analyzing protocols that prevent third parties or the general public from accessing private (encrypted) messages. Modern classical cryptography is based on several main features of information security such as data confidentiality, data integrity, authentication, and non-repudiation. WebCryptography is a continually evolving field that drives research and innovation. The Data Encryption Standard (DES), published by NIST in 1977 as a Federal Information Processing Standard (FIPS), was …
