java url加密_Java实现url加密处理的方法示例

大家好，又见面了，我是你们的朋友全栈君。

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 {

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));

}

}
