百度反推算法PHP代碼
前段時(shí)間百度反推很火，我在某個(gè)算法交流群里呆了數(shù)天都沒(méi)看出個(gè)所以然來(lái)。沒(méi)想到幾天沒(méi)有上線百度反推都出來(lái)了。
在發(fā)布百度反推軟件之前，先把曹操之前搜集到的百度反推PHP發(fā)布出來(lái)看看。
代碼僅供參考思路，實(shí)際上經(jīng)過(guò)測(cè)試發(fā)現(xiàn)已經(jīng)無(wú)法通過(guò)解析出來(lái)的地址實(shí)現(xiàn)跳轉(zhuǎn)。
百度反推PHP轉(zhuǎn)換代碼一
使用方法：修改函數(shù)url的值為自己url，即可生成對(duì)應(yīng)的百度快照url。

下面一段代碼本人也不太看得明白，似乎是url加密，僅供參考!
<?php
$time = time() . rand(1000, 9999);
$data = "{$time}###http://www.yetiskinlerchat.com"; // 被加密信息

$encrypt = encrypt($data, $key);
$decrypt = decrypt($encrypt, $key);
echo $encrypt, "

function encrypt($data, $key) {
$key = md5($key);
$x = 0;
$len = strlen($data);
$l = strlen($key);
for ($i = 0; $i < $len; $i++) {
if ($x == $l) {

}
$char.= $key{$x};
