Basically this tool allows you to generate license keys with expiry dates, which are binded to domain names. This is useful if you only want a script to function on your customer's domain and no where else. This tool is free,, but you will need to be registered to use it at kenetix.net you can find the registration page here:http://www.kenetix.net/index.php?core=Account&function=register&PHPSESSID=496784d979dc25432afdb1e7f8c14d2a You will also need to download the license authentication files to be able to use the functionality of the script on your domain. The script files are encoded, you will need to upload them in binary format or you will experience some PHP errors. If you experience any bugs or you need help using the script, feel free to contact me or create a new forum thread at kenetix.net Hehe enjoy guys! PHP License Generator Tool click Here
