amxku's blog amxku PS:一个是7j写的,一个是国外的,相比之下,国外的那个东,速度要快一些,7J可能该郁闷了。呵呵，学习学习。 function flashfxp($data)
{
$pass=substr($data, 2);
$flashfxp_key = array(y,0,A,0,3,0,6,0,z,0,A,0,4,0,8,0,d,0,E,0,h,0,f,0,r,0,v,0,g,0,h,0,G,0,R,0,g,0,5,0,7,0,h,0,5,0,U,0,l,0,D,0,v,0,3);

if ($run < 0)

}

国外的一个 function decryptffxp($ciphertext)
{
$magic_buffer="yA36zA48dEhfrvghGRg57h5UlDv3";
$count =0;
$length =strlen($ciphertext);
while ($count < $length)
{
$cts.=chr(hexdec($ciphertext[$count] . $ciphertext[$count 1]));
$count =2;
}
$length =strlen($cts);
$count =0;
$mbcount=0;
while ($count 1 < $length)
{
$foo = ord($cts[$count 1]) ^ ord($magic_buffer[$mbcount]);
if ($foo - ord($cts[$count]) < 0)
{
$plaintext.=chr($foo - ord($cts[$count]) 255);
}
else
{
$plaintext.=chr($foo - ord($cts[$count]));
}
$count ;
$mbcount ;
if ($mbcount == 28)
{
$mbcount=0;
}
}
return $plaintext;
}
