我想加密字符串 [英] i want to encrpyt string

问题描述

您好，

点击加密后我想加密Hello world按钮字符串应该用不同的加密格式写。



例如：

Hello,
I want to encrypt "Hello world" after click on encrypt Button string should be written in different encrypted format.

For example:

Actual string        out put (i want)  

Hello world          rdIaJwuMRHupXSA7NDjf+Q==         
Hello world          +I3MFzYshgcXg0OCKI6WJQ==       
Hello world          3fYzgRUkKdc6A2hNnKM8lA==

其加密功能

Its encrypt function

public static string Base64Encode(string sData)
  {
      try
      {
          byte[] toEncodeAsBytes = System.Text.Encoding.Unicode.GetBytes(sData);
          string returnValue = Convert.ToBase64String(toEncodeAsBytes);

          return returnValue;
      }
      catch (Exception ex)
      {
          throw new Exception("Error in base64Encode" + ex.Message);
      }
  }

private const string Chars =abcdefgijkmnopqrstwxyz23456789abcdefgijkmnopqrstwxyz;
private readonly Random _rng = new Random();

public static string Base64Encode(string sData)
  {
      try
      {
          byte[] toEncodeAsBytes = System.Text.Encoding.Unicode.GetBytes(sData);
          string returnValue = Convert.ToBase64String(toEncodeAsBytes);
             string newencryptName = RandomString(15).ToString() + returnValue;
          return newencryptName;
      }
      catch (Exception ex)
      {
          throw new Exception("Error in base64Encode" + ex.Message);
      }
  }

private string RandomString(int size)
{
var buffer = new char[size];

for (var i = 0; i < size; i++)
{
buffer[i] = Chars[_rng.Next(Chars.Length)];
}
return new string(buffer);
}
