WebCodes and ciphers are forms of secret communication. A code replaces words, phrases, or sentences with groups of letters or numbers, while a cipher rearranges letters or uses substitutes to disguise the message. This process is called encryption or enciphering. The science that studies such secret communication is called cryptology.
