Php decrypts eval (gzinflate (str_rot13 (base64_decode

From hacker notes

In this way, the encryption author is very rogue and abnormal, because it is easy to know such encryption and cracking, but it is still abnormal to encrypt the code countless times.

I wrote the following two PHP files:

// B. PHP

<? Php
$Str=file_get_contents(2.txt );
While (preg_match ("/eval (gzinflate (str_rot13 (base64_decode ([^] *)/", $ str, $ match )){
$Fpw.fopen(1.txt, w );
Fputs ($ fp, $ match [1]);
Fclose ($ fp );
System (php a. php );
$Str=file_get_contents(2.txt );
}
?>

// A. PHP

<? Php
$Str=file_get_contents(1.txt );
$ Str = base64_decode ($ str );
$ Str = str_rot13 ($ str );
$ Str = gzinflate ($ str );
$Fpw.fopen(2.txt, w );
Fputs ($ fp, $ str );
Fclose ($ fp );
?>
Save your code as 2.txtand run the following command in CMD:
Php B. PHP
After a while, the program is executed. 2. TXT is the decrypted code.
