"WebCiphers. Although most people claim they're not familar with cryptography, they are often familar with the concept of ciphers, whether or not they are actually concious of it.. Ciphers are arguably the corner stone of cryptography. In general, a cipher is simply just a set of steps (an algorithm) for performing both an encryption, and the corresponding decryption.
