Secret cdes(密码) keep messages private.Banks，cmpanies，and gvernment agencies use secret cdes in ding business，especially when infrmatin is sent by cmputer.
Peple have used secret cdes fr thusands f years. 36 Cde breaking never lags(落后) far behind cde making.The science f creating and reading cded messages is called cryptgraphy.
There are three main types f cryptgraphy. 37 Fr example，the first letters f “My elephant eats t many eels” spell ut the hidden message “Meet me”.
38 Yu might represent each letter with a number，fr example.Let’s number the letters f the alphabet，in rder，frm 1 t 26.If we substitute a number fr each letter，the message “Meet me” wuld read “13 5 5 20 13 5”.
A cde uses symbls t replace wrds，phrases，r sentences.T read the message f a real cde，yu must have a cde bk. 39 Fr example，“bridge” might stand fr “meet” and “ut” might stand fr “me”.The message “Bridge ut” wuld actually mean “Meet me”. 40 Hwever，it is als hard t keep a cde bk secret fr lng.S cdes must be changed frequently.
A.It is very hard t break a cde withut the cde bk.
B.In any language，sme letters are used mre than thers.
C.Only peple wh knw the keywrd can read the message.
D.As lng as there have been cdes，peple have tried t break them.
E.Yu can hide a message by having the first letters f each wrd spell it ut.
F.With a cde bk，yu might write dwn wrds that wuld stand fr ther wrds.
G.Anther way t hide a message is t use symbls t stand fr specific letters f the alphabet.
