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 groundbreaking for its time but would fall far short of the levels of protection needed today. As our electronic networks grow increasingly open ... 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 ...
