#php和java加解密 java加解密

本文针对之前出现的Java与PHP加解密对接中出现的乱码问题，提供了一个新的加解密对接方案，确保数据在两种语言间正确无误地加解密传输。

之前写过一个java和php的加解密对接文章，好像解密后有部分字符串乱码，现在重新给一个加解密的对接方案：

java代码：

import java.util.UUID;

import org.apache.commons.codec.binary.Base64;


public class Base64Utility extends Base64 {

    private static final char   last2byte   = (char) Integer.parseInt("00000011", 2);
    private static final char   last4byte   = (char) Integer.parseInt("00001111", 2);
    private static final char   last6byte   = (char) Integer.parseInt("00111111", 2);
    private static final char   lead6byte   = (char) Integer.parseInt("11111100", 2);
    private static final char   lead4byte   = (char) Integer.parseInt("11110000", 2);
    private static final char   lead2byte   = (char) Integer.parseInt("11000000", 2);
    /**
     * "+" -> "*"; "/" -> "-"
     */
    private static final char[] encodeTable = new char[] { 'A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y', 'Z', 'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm',
            'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z', '0', '1', '2', '3', '4', '5', '6', '7', '8', '9', '*', '-' };

    /**
     * @param binaryData
     *            binary data to encode
     * @return String containing Base64 characters
     * @since 1.4
     */
    public static String encodeBase64URLSafeString2(byte[] from) {
        StringBuffer to = new StringBuffer((int) (from.length * 1.34) + 3);
        int num = 0;
        char currentByte = 0;
        for (int i = 0; i < from.length; i++) {
            num = num % 8;
            while (num < 8) {
                switch (num) {
                    case 0:
                        currentByte = (char) (from[i] & lead6byte);
                        currentByte = (char) (currentByte >>> 2);
                        break;
