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. WebCodes have been usedthroughout history whenever people wanted to keep messages private. Cryptology has long been employedby governments, military, businesses, and … Modern cryptography [ edit] Claude Shannon [ edit]. Claude E.
