Java实现url加密处理的方法示例
本文实例讲述了java实现url加密处理的方法。分享给大家供大家参考,具体如下:
package test;
import java.security.Key;
import java.security.SecureRandom;
import javax.crypto.Cipher;
import javax.crypto.KeyGenerator;
import sun.misc.BASE64Decoder;
import sun.misc.BASE64Encoder;
public class ThreeDES {
egnvmz public static String crypt(String content,String password,int i){
try {
KeyGenerator generator = KeyGenerator.getInstance("AES");
generator.init(new SecureRandom(password.getBytes()));
Key key = generator.generateKey();
generator = null;
if(i == 1){
return getEncString(content,key);
}
else if(i == 2){
return getDesString(content,key);
}
} catch (Exception e) {
return null;
}
return null;
}
/**
* 加密String明文输入,String密文输出
*
* @param strMing
* @return
*/
private static String getEncString(String strMing,Key key) {
byte[] byteMi = null;
byte[] byteMing = null;
String strMi = "";
BASE64Encoder base64en = new BASE64Encoder();
try {
byteMing = strMing.getBytes("UTF8");
byteMi = getEncCode(byteMing,key);
strMi = base64en.encode(byteMi);
} catch (Exception e) {
e.printStackTrace();
} finally {
base64en = null;
byteMing = null;
byteMi = null;
}
return strMi;
}
/**
* 解密 以String密文输入,String明文输出
*
* @param strMi
* @return
*/
private static String getDesString(String strMi, Key key) {
BASE64Decoder base64De = new BASE64Decoder();
byte[] byteMing = null;
byte[] byteMi = null;
String strMing = "";
try {
byteMi = base64De.decodeBuffer(strMi);
byteMing = getDesCode(byteMi,key);
strMing = new String(byteMing, "UTF8");
} catch (Exception e) {
e.printStackTrace();
} finally {
base64De = null;
byteMing = null;
byteMi = null;
}
return strMing;
}
/**
* 加密以byte[]明文输入,byte[]密文输出
*
* @param byteS
* @return
*/
private static byte[] getEncCode(byte[] byteS,Key key) {
byte[] byteFina = null;
Cipher cipher;
try {
cipher = Cipher.getInstance("AES");
cipher.init(Cipher.ENCRYPT_MODE, key);
byteFina = cipher.doFinal(byteS);
} catch (Exception e) {
e.printStackTrace();
} finally {
cipher = null;
}
return byteFina;
}
/**
* 解密以byte[]密文输入,以byte[]明文输出
*
* @param byteD
* @return
*/
private static byte[] getDesCode(byte[] byteD,Key key) {
Cipher cipher;
byte[] byteFina = null;
try {
cipher = Cipher.getInstance("AES");
cipher.init(Cipher.DECRYPT_MODE, key);
byteFina = cipher.doFinal(byteD);
} catch (Exception e) {
e.printStackTrace();
} finally {
cipher = null;
}
return byteFina;
}
public static void main(String[] args) {
System.out.println(ThreeDES.crypt("bindMobile=13023130171&fenjihao=107", "bbbbb", 1));
System.out.println(ThreeDES.crypt("GT+F0fcFNGiq73/+FaX9pK9n9zqxwqz9sZ7MQdSp1BxWJXWn7EwnvniQpAOaGi0W", "bbbbb", 2));
}
}
