Cryptology for Kids Introduction: A code is a system of symbols, letters, words, or signals that are used instead of ordinary words and numbers to send messages or store information. A code is used to keep the message short or to keep it secret. Codes and ciphers are forms of secret communication. A code replaces words, phrases, or sentences WebThis library contains a fast implementation of the DES encryption algorithm. There are two phases to the use of DES encryption. The first is the generation of a DES_key_schedule from a key, the second is the actual encryption. A DES key is of type DES_cblock.
