某php加密算法的java版本

很久以前弄的了，作个记录，

不说了，上代码：

function encpw($src){$spw=$src;//$spw=base64_decode($src);$Xbox1 = array( chr(75), chr(99), chr(200), chr(24), chr(64), chr(10), chr(23), chr(52) );$Xbox2 = array( chr(12), chr(28), chr(21), chr(100), chr(29), chr(44), chr(87), chr(23) );$Xbox3 = array( chr(23), chr(11), chr(33), chr(134), chr(123), chr(29), chr(12), chr(12));$Xbox4 = array( chr(39), chr(22), chr(19), chr(103), chr(145), chr(199),chr(20), chr(77) );$len = strlen( $spw); for ( $c = 0; $c <$len; $c++ ){$index = $c % 8;$spw[$c] =$spw[$c]^ $Xbox1[$index];$spw[$c] =$spw[$c]^ $Xbox2[$index];$spw[$c] =$spw[$c]^ $Xbox3[$index];$spw[$c] =$spw[$c]^ $Xbox4[$index];}for ( $pos=0; $pos < $len; $pos++ ){if ( ord($spw[$pos])==0){ $spw[$pos] = $src[$pos];}}return base64_encode($spw);}

java:

public static String decode(String s){String result = "";int []Xbox1 = {(int)75,(int)99,(int)200,(int)24,(int)64,(int)10,(int)23,(int)52};int []Xbox2 = {(int)12,(int)28,(int)21,(int)100,(int)29,(int)44,(int)87,(int)23};int []Xbox3 = {(int)23,(int)11,(int)33,(int)134,(int)123,(int)29,(int)12,(int)12};int []Xbox4 = {(int)39,(int)22,(int)19,(int)103,(int)145,(int)199,(int)20,(int)77};StringBuffer s1 = new StringBuffer(s);byte [] k = new byte[s1.length()];int index; for ( int i = 0; i < s1.length(); i++ ){ index = i % 8; k[i] = (byte)(s.charAt(i)^Xbox1[index]^Xbox2[index]^Xbox3[index]^Xbox4[index]);}for ( int i = 0; i < k.length; i++ ){ if(((int)k[i])==0) { k[i] = (byte)s.charAt(i); }} BASE64Encoder b = new BASE64Encoder(); result = b.encode(k);return result;}
