(string strSource)方法用来对比比较重要的信息进行加密
Dencrypting(string source)方法将已加密的信息进行解密

Java代码

using System.Security.Cryptography;
using System.IO;
using System.Text;

Java代码

public static string Encrypting(string strSource)
{
byte[] bytln = System.Text.Encoding.Default.GetBytes(strSource);
byte[] iv = {102,16,93,156,78,4,218,32 };//定义偏移量
byte[] key = {55,103,246,79,36,99,167,3 };//定义密钥
//实例DES加密类
DESCryptoServiceProvider mobjCryptoService = new DESCryptoServiceProvider();
mobjCryptoService.Key = iv;
mobjCryptoService.IV = key;
ICryptoTransform encrypto = mobjCryptoService.CreateEncryptor();
//实例MemoryStream流加密文件
System.IO.MemoryStream ms = new System.IO.MemoryStream();
CryptoStream cs = new CryptoStream(ms,encrypto ,CryptoStreamMode.Write );
cs.Write(bytln ,0,bytln.Length );
cs.FlushFinalBlock();
return System.Convert.ToBase64String(ms.ToArray ());
}
public static string Dencrypting(string source)
{
try
{
//将解密字符串转成字节数组
byte[] bytln = System.Convert.FromBase64String(source);
byte[] iv = { 102, 16, 93, 156, 78, 4, 218, 32 };//定义偏移量
byte[] key = { 55, 103, 246, 79, 36, 99, 167, 3 };//定义密钥
DESCryptoServiceProvider mobjCryptoService = new DESCryptoServiceProvider();
mobjCryptoService.Key = iv;
mobjCryptoService.IV = key;
//实例流进行解密
System.IO.MemoryStream ms = new System.IO.MemoryStream(bytln ,0,bytln .Length );
ICryptoTransform encrypto = mobjCryptoService.CreateDecryptor();
CryptoStream cs = new CryptoStream(ms, encrypto, CryptoStreamMode.Read);
StreamReader strd = new StreamReader(cs, Encoding.Default);
return strd.ReadToEnd();
}
catch (Exception ex)
{
throw new Exception("在文件解密的时候出现错误"+ex.Message );
}
}
