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 ... Webcipher: A cipher (pronounced SAI-fuhr ) is any method of encrypting text (concealing its readability and meaning). It is also sometimes used to refer to the encrypted text message itself although here the term ciphertext is preferred. Its origin is the Arabic sifr , meaning empty or zero . In addition to the cryptographic meaning, cipher also ...
