I have a problem regarding encrypting the footer file of my Wordpress theme. I am looking for some one expert in PHP and Wordpress function - preferably from India. How can I use some function in function.php to implement license key/password for removing footer link? I know PHP can't be encrypted in a way that the user can't decrypt. I know that the most common method is using gzinflate and base64_decode. but people can easily decrypt that. I am looking for some stronger encryption method so that I can use it in my themes. Please don't wast my time, if you are new in this field. add me in skype. My ID is npnhome.
