RSA 在C#里简单实现
摘要:1.选择两个大素数:p,q;2.计算所得n:n=p*q;3.计算中间结果t:t=(p-1)*(q-1);4.选择一个e:要求e和t的最大公因数是1(也就是e与t互素);5.计算所得d:d*e mod t=1,就是说要求d和e的乘积除以t余1;(n,e)就是公钥,(n,d)就是私钥 using Sys

KMP算法
摘要:KMP算法的关键在于模式字符串的处理,就是如何求next数组的值我以为关键点就在于就是要找到k的值ababacde如果到最后一个a的话,最前面的ab和最后一个a前面的ab相等,所以k为2abacacde如果到最后一个a的话,a前面的c,在abac里中,没有字符满足,所以就是0
