php 3DES加密如何相容Java

Java源碼：

import java.security.Security;import javax.crypto.Cipher;import javax.crypto.SecretKey;import javax.crypto.spec.SecretKeySpec;public class ThreeDES {private static final String Algorithm = "DESede"; //定義 密碼編譯演算法,可用 DES,DESede,Blowfish        //keybyte為加密金鑰，長度為24位元組    //src為被加密的資料緩衝區（源）    public static byte[] encryptMode(byte[] keybyte, byte[] src) {       try {            //產生密鑰            SecretKey deskey = new SecretKeySpec(keybyte, Algorithm);            //加密            Cipher c1 = Cipher.getInstance(Algorithm);            c1.init(Cipher.ENCRYPT_MODE, deskey);            return c1.doFinal(src);        } catch (java.security.NoSuchAlgorithmException e1) {            e1.printStackTrace();        } catch (javax.crypto.NoSuchPaddingException e2) {            e2.printStackTrace();        } catch (java.lang.Exception e3) {            e3.printStackTrace();        }        return null;    }    //keybyte為加密金鑰，長度為24位元組    //src為加密後的緩衝區    public static byte[] decryptMode(byte[] keybyte, byte[] src) {          try {            //產生密鑰            SecretKey deskey = new SecretKeySpec(keybyte, Algorithm);            //解密            Cipher c1 = Cipher.getInstance(Algorithm);            c1.init(Cipher.DECRYPT_MODE, deskey);            return c1.doFinal(src);        } catch (java.security.NoSuchAlgorithmException e1) {            e1.printStackTrace();        } catch (javax.crypto.NoSuchPaddingException e2) {            e2.printStackTrace();        } catch (java.lang.Exception e3) {            e3.printStackTrace();        }        return null;    }    //轉換成十六進位字串    public static String byte2hex(byte[] b) {        String hs="";        String stmp="";        for (int n=0;n
