It is obvious that the use of some kind of PHP code obfuscation tool confused under the Google Web search, problem solving, to meet the same problem of friends a convenience.
Decrypt PHP Files:
Copy CodeThe code is as follows:
$filename = "GlobalAction.class.php";//File to decrypt
$lines = file ($filename);//0,1,2 Line
First time Base64 decryption
$content = "";
if (Preg_match ("/o0o0000o0\ ('. * ')/", $lines [1], $y))
{
$content =str_replace ("O0o0000o0 ('", "", $y [0]);
$content =str_replace ("')", "" ", $content);
$content =base64_decode ($content);
}
Find key in Base64 decrypted content for the first time
$decode _key= "";
if (Preg_match ("/\), '. * ',/", $content, $k))
{
$decode _key=str_replace ("), '", "", $k [0]);
$decode _key=str_replace ("',", "", $decode _key);
}
Find the length of the string to intercept
$str _length= "";
if (Preg_match ("/,\d*\),/", $content, $k))
{
$str _length=str_replace ("),", "", $k [0]);
$str _length=str_replace (",", "", $str _length);
}
Ciphertext after intercepting file encryption
$Secret =substr ($lines [2], $str _length);
Echo $Secret;
Direct reduction of ciphertext output
echo " ' abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz0123456789+/').
