DES加密 java与.net可以相互加密解密的方法
我.net/Java程序员。今天让C#和Java数据加密交互。通过这个方法可以实现java和C#相互加密与解密 并能保持解密出来一致。
话不多说，看代码
C#代码如下
package web_test;
import javax.crypto.Cipher;
import javax.crypto.SecretKey;
import javax.crypto.SecretKeyFactory;
import javax.crypto.spec.DESKeySpec;
import javax.crypto.spec.IvParameterSpec;
import javax.crypto.spec.SecretKeySpec;
public class AESUtils {
private byte[] desKey;
//解密数据
public static String decrypt(String message, String key) throws Exception {
byte[] bytesrc = convertHexString(message);
Cipher cipher = Cipher.getInstance("DES/CBC/PKCS5Padding");
DESKeySpec desKeySpec = new DESKeySpec(key.getBytes("UTF-8"));
SecretKeyFactory keyFactory = SecretKeyFactory.getInstance("DES");
SecretKey secretKey = keyFactory.generateSecret(desKeySpec);
IvParameterSpec iv = new IvParameterSpec(key.getBytes("UTF-8"));
cipher.init(Cipher.DECRYPT_MODE, secretKey, iv);
byte[] retByte = cipher.doFinal(bytesrc);
return new String(retByte);
}
public static byte[] encrypt(String message, String key)
throws Exception {
Cipher cipher = Cipher.getInstance("DES/CBC/PKCS5Padding");
DESKeySpec desKeySpec = new DESKeySpec(key.getBytes("UTF-8"));
SecretKeyFactory keyFactory = SecretKeyFactory.getInstance("DES");
SecretKey secretKey = keyFactory.generateSecret(desKeySpec);
IvParameterSpec iv = new IvParameterSpec(key.getBytes("UTF-8"));
cipher.init(Cipher.ENCRYPT_MODE, secretKey, iv);
return cipher.doFinal(message.getBytes("UTF-8"));
}
public static byte[] convertHexString(String ss) {
byte digest[] = new byte[ss.length() / 2];
for (int i = 0; i < digest.length; i++) {
String byteString = ss.substring(2 * i, 2 * i + 2);
int byteValue = Integer.parseInt(byteString, 16);
digest[i] = (byte) byteValue;
}
return digest;
}
public static String toHexString(byte b[]) {
StringBuffer hexString = new StringBuffer();
for (int i = 0; i < b.length; i++) {
String plainText = Integer.toHexString(0xff & b[i]);
if (plainText.length() < 2)
plainText = "0" + plainText;
hexString.append(plainText);
}
return hexString.toString();
}
}
static void Main(string[] args)
{
string DES_Key = "12345678";
Console.WriteLine("----------------------------------------------------------------------");
localhost.testService ts = new localhost.testService();
//接收java WebService服务loadname方法返回的值
int c = ts.loadname(456);//ts.loadname(456)代表一个int类型的值，你可以写成 int c=123456;等等
//接收java WebService服务loadname2方法返回的值
string d = ts.loadname2();
//处理java传过来的密文
string jiamijava = AESHelper.DESEnCodeJava(d, DES_Key);
//解密java处理的密文
string jiemi = AESHelper.DESDeCode(jiamijava, DES_Key);
//打印解密后的密文
Console.WriteLine(jiemi);
//加密C#数据
string jiami = AESHelper.DESEnCode("我太难了,反倒是减肥广东省", DES_Key);
//接收java WebService服务loadname4方法返回的值
string cd = ts.loadname4(jiami);
//处理java传过来的密文
jiamijava = AESHelper.DESEnCodeJava(cd, DES_Key);
//解密java处理的密文
jiemi = AESHelper.DESDeCode(jiamijava, DES_Key);
//打印解密后的密文
Console.WriteLine(jiemi);
//接收java WebService服务datime方法返回的值
string c1 = ts.datime(DateTime.Now.ToString("yyyy-MM-dd hh:mm:ss"));
Console.WriteLine(ts.dble(623.23687));
Console.WriteLine(c);
//Console.WriteLine(d);
Console.WriteLine(c1);
Console.WriteLine(c + "===" + jiemi);
//加密C#数据
jiami = AESHelper.DESEnCode("", DES_Key);
//接收java WebService服务str方法返回的值
string str = ts.str(jiami);
//处理java传过来的密文
jiamijava = AESHelper.DESEnCodeJava(str, DES_Key);
//解密java处理掉密文
jiemi = AESHelper.DESDeCode(jiamijava, DES_Key);
Console.WriteLine("================================================");
Console.WriteLine(jiemi);
Console.WriteLine("================================================");
Console.Read();
}
