实现加密字符串技术，程序根据概率统计自动绘制一张加密表，然后对输入字符串进行加密和自动解密工作，不过为了节省时间，只能对小写字母进行加密-Technology to achieve the encrypted string, the program automatically based on probability and statistics to draw an encrypted form, and then the input string to encrypt and decrypt

代替密码字符串频率统计,重复间隔统计，用于单表或多表代替密码的破解-Instead of the password string frequency statistics, repeat interval statistics for a single table or multi-table instead of a password crack

实现了古典密码的单表置换密码,Test 同来统计字母出现的次数,"Key.txt" 保存用户的一串字符串，用来生成密钥。并且实现了自动破解-Achieve a classic single-table replacement password password
