实现一个简单加解密系统,要求如下:
(1)输入要加密的原文,长度不小于30个字母;
(2)输入密钥长度L及用来产生密钥的英文字母(个数>=L);
注:一个有效的密钥由L(3<=L<=15)个小写英文字母组成,至少有一个元音字母( a , e , i , o 或者 u ),至少有两个辅音字母(除去元音以外的字母)。
(3)选择加密功能,可对原文进行加密;
(4)选择解密功能,可对密文进行解密。 -Implement a simple encryption and decryption system requirements are as follows: (1) Enter the encrypted text, the length is not less than 30 letters (2) Enter the key length L and used to generate the key in English letters (number> = L ) Note: a valid key from the L (3 < = L < = 15) composed of a lower-case letters, at least one vowel letter ( ' a' , ' e' , ' i' , ' o' or ' u' ), at least two consonant letters (other than the removal of vowel letters). (3) Select encryption can encrypt the original text (4) Select decryption functions, can decrypt the ciphertext.
