Description:
------------
I am setting "blenc.key_file" in php.ini to a relative path:

    blenc.key_file="./__blenc_keys"

If I do so and run the encrypted script then it cannot find __blenc_keys file and an error occurs:

    Fatal error: blenc_compile: Validation of script 
    'C:\phpdesktop\phpdesktop-chrome\www\my_source_encoded.php' failed,
    cannot execute. in Unknown on line 0

It seems that when running encrypted script BLENC thinks that current directory is php/.

This behavior is inconsistent, because when running normal php script (not encrypted, resides in www/encrypt.php), then BLENC finds the blenc keys file just fine in www/ directory. But when you run encrypted "www/my_source_encoded.php" then it looks for blenc keys file in php/ directory.

I know that it's best to use an absolute path and it will work fine, but this is still a bug that can cause headache.

I can make it work with relative path using this trick:

    blenc.key_file="./../www/__blenc_keys"

This works for both cases whether BLENC thinks current directory is www/ or php/ (assuming that both these dirs have common upper directory eg. phpdesktop/www/ and phpdesktop/php/ in my case).

Tested with BLENC 1.1.4b.
