as [b]encryption_key[/b] need not key, but key file. examle:
[code]
<?php
blenc_encrypt($source_code, "my_source_encoded.php", 'IMyxRIF3w+oTRCf4VOnRvw=='); // invalid
blenc_encrypt($source_code, "my_source_encoded.php", file_gets_contents(ini_get('blenc.key_file'))); // invalid
blenc_encrypt($source_code, "my_source_encoded.php", ini_get('blenc.key_file')); //valid
?>
[/code]
for encoding key file may have more that 1 key. code will be run, but php return warning if valid key not first.
