在asp.net中加密和解密 [英] Encrypt and Decrypt in asp .net

问题描述

有人可以给我代码加密和解密一个字符串在asp .net

Can someone give me the code to Encrypt and Decrypt a string in asp .net

推荐答案

你好Sameer，



我建议你尝试自己的加密技术，因为C＃有更多的加密方法。

Hi Sameer,

I would suggest you to try your own encryption technology since C# has more number of encryption methodology.

private string encodeStr =
            @"!#

％&'（）* +， - 。/ 0123456789：;< =>？@ ABCDEFGHIJKLMNOPQRSTUVWXYZ [\] ^ _`abcdefghijklmnopqrstuvwxyz {|}〜;

private string decodeStr =
@ @ ABCDEFGHIJKLMNO0123456789：;< =>？pqrstuvwxyz {|}〜！＃

%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz{|}~"; private string decodeStr = @"@ABCDEFGHIJKLMNO0123456789:;<=>?pqrstuvwxyz{|}~!#

％& amp ;（）* +， - /`ABCDEFGHIJKLMNOPQRSTUVWXYZ [\] ^ _。


protected string encodeString（ string rawText）
{
string cipherText = string .Empty;
foreach （ char rawChar in rawText）
{
cipherText + = encodeStr.ElementAt（decodeStr.IndexOf（rawChar））;
}
return cipherText;
}

// 自定义解密方法
protected string decodeString（ string cipherText）
{
string rawText = string .Empty;
foreach （ char cipherChar in cipherText）
{
rawText + = decodeStr.ElementAt（encodeStr.IndexOf（cipherChar））;
}
return rawText;
}

%&'()*+,-./`abcdefghijklmnoPQRSTUVWXYZ[\]^_"; protected string encodeString(string rawText) { string cipherText = string.Empty; foreach (char rawChar in rawText) { cipherText += encodeStr.ElementAt(decodeStr.IndexOf(rawChar)); } return cipherText; } //Custom Decryption method protected string decodeString(string cipherText) { string rawText = string.Empty; foreach (char cipherChar in cipherText) { rawText += decodeStr.ElementAt(encodeStr.IndexOf(cipherChar)); } return rawText; }

函数调用：

encodeString（输入要加密的字符串）;

decodeString（输入要解密的字符串）;



好​​的，如果你不是准备尝试自己的加密方法，看看这里 [ ^ ]和使用.NET加密/解密 [ ^ ]

Function call:
encodeString("input String to encrypt");
decodeString("input String to decrypt");

Ok if you not ready to try your own encryption methods, have a look at here[^]andEncryption/Decryption with .NET[^]
