BEFOR E WE TALK ABOUT THE PROGRAM.ITSELF, LET' S LOOK AT SOME.CRYPTANALYSIS TERMS. FIR ST, THE.MESSAGE THAT IS TO BE PUT IN SEC RET.FORM IS CALLED PLAINTEXT. THE.CRYPT OGRAPHER USES A CIPHER OR A CODE.TO TRAN SFORM PLAINTEXT INTO A SECRET.MESSAGE... WHAT'S THE DIFFERENCE BETWEEN A CODE.A ND A CIPHER? WHILE THERE IS NO.SHARP D IVIDING LINE, THINK OF A CODE.AS A GROUP OF NUMBERS OR LETTERS.STANDING FOR WHOL E WORDS OR PHRASES..TWO CODEWORDS MIGHT LOOK ALIKE BUT.HAVE DIFFERENT MEANINGS. WHILE THE.LETTERS "PDSFDF" COULD STAND F OR "BUY.A YEAR'S SUBSCRIPTION TO LOADSTA R";."PDSFDA" MIGHT MEAN "HIJACK ONE.KILO GRAM OF WEAPONS-GRADE PLUTONIUM.".THE RE CEIVER MUST USUALLY HAVE A.CODEBOOK TO D ECODE A CODED MESSAGE...
