Description: 移位密码、代换密码的加密及解密 实现移位密码:k表示26个字母向前循环位移的字符个数 加密: 输入:k,以及小写表示的明文字母,输出:大写字母表示的密文 解密:输入: k,以及大写字母表示的密文,输出:小写字母表示的明文 例如,当k=11时 明文:wewillmeetatmidnight 密文:HPHTWWXPPELEXTOYTRSE 实现代换密码 例如输入密匙guangzhouuniversity,则建立字母对应关系: a b c d e f g h i j K l m G U A N Z H O I V E R S T n o p q r s t u v w X y z Y B C D F J K L M P Q W X 字母对应关系的说明:把密匙按照a-z的顺序对应,去掉重复字母,如guangzhouuniversity中的g第二次出现时被滤掉, 在n对应Y之后,把在密匙中没出现过的其他字母按顺序排列:BCDFJ…… -translocation password substitution password encryption and decryption of achieving shift Password : k said 26 letters forward displacement cycle of the number of characters encryption : Admission : k, and explicitly expressed in lowercase letters, output : capital letters said the ciphertext declassified : Admission : k, and the uppercase letters dense text output : lowercase letters explicitly said for example, when k = 11:00 explicit : wewillmeetatmidnight dense text : HPHTWWXPPELEXTOYTRSE achieve import substitution such as password key guangzho uuniversity, the establishment of correspondence between letters : a b c d e f g h i j k l m G U A N Z H O R E V I S T n o p q r s t u v w x y z Y B C D F J K L M P Q W X correspondence between letters Note : In accordance with a key put-z corr
