Footer link protection in wordpress themes?

Can someone please point me to a script or something for this? My searches only turn up link sales threads.

Thanks, Matt

 

Try this: http://www.byterun.com/free-php-encoder.php

 

i got the same question with the OP

 

Thanks! Does that rely on a site to work, or will it still work fine if the byterun site (or maybe another site) is offline?

Thanks, Matt

 

please post other sites...

 

Does anyone know?
