Today i see a php script, that is encrypted with
eval(gzinflate(base64_decode('JUNK_CODE_HERE')));
I tried to decrypt the script, but it have many levels of recurring gzinflate, base64_decode encryption. If some one runs a script encrypted like this, it take more server resource to do all decryption, must consider ioncube, phpshield or zend encoder for encoding php scripts.
I have written a php script that will decrypt scripts encoded with eval, gzinflate, base64_decode. The script can be modified to decrypt other combination of encryption like str_rot13
