本文介绍了使用RSA算法的密码学的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我想在不使用密码学类的情况下对任何字符串进行加密和解密(使用RSA算法)我写了一个代码，请告诉我我的错误在哪里我做错了....

I want to encrypt and decrypt (using RSA algorithm) any string without using cryptography classes i wrote a code please tell me about my mistake where i do wrong....

protected void Button1_Click(object sender, EventArgs e) { string ab; int unicode = 0, a = 0, cnt = 0, i = 0, j = 0; int[] number=new int[1000]; double[] c1=new double[1000]; double[] unicode1 = new double[1000]; ab = TextBox1.Text; double d; foreach (char c in ab) { unicode = c; Console.WriteLine(unicode < 128 ? ASCII:{0} : NON-ASCII:{0}, unicode); number[i] = unicode; i++; } double p = 0, q = 0, o = 0; p = (double)Convert.ToInt64(TextBox2.Text); q = (double)Convert.ToInt64(TextBox3.Text); double n = p * q; double q1 = (p - 1) * (q - 1); Response.Write(q1); o = (double)Convert.ToInt64(TextBox4.Text); d = (Math.Pow(o, -1)); d = d % q1; for (j = 0; j< i; j++) { c1[j]=(Math.Pow(number[j],n))%n; Response.Write(c1[j]); } for (j = 0; j<i;> { unicode1[j]=(Math.Pow(c1[j],d))%n; Response.Write("unicode1" + unicode1[j]); } double unicode1 = (int)(Math.Pow(c1,d)) % n; for (j = 0; j<i;> { string str = char.ConvertFromUtf32((int)unicode1[j]); Response.Write(str); } string str = char.ConvertFromUtf32((int)unicode); Response.Write(str); }

推荐答案

应该使用内置的RSACryptoServiceProvider类:-) 参见 C#.NET中的公钥RSA加密 [ ^ ] Should probably use the built-in RSACryptoServiceProvider class :-) see Public Key RSA Encryption in C# .NET[^]
