i wonder if i create plugin for wordpress, which the best software to encrypt my plugin, any body have experience thank's
Encryption of WP plugins does happen, but usually there are little to no reason for doing so. Most PHP-encryptions can be broken, or reversed, so if anyone really wants to, they will be able to read and change your code. There is a reason why it's called "open source" - I suggest finding other ways to make a buck on the plugin, either by offering value that isn't readily available in other plugins, or by offering a service that is so much better than any existing plugins that it will be rumoured to be the best, and spread widely - ask for donations, or charge for downloads - believe me, there will be money to be made by this, regardless of whether or not the script is encrypted.
Well maybe zend it but i havent seen encrypted plugins as such only encrypted footers in the template which are reversible
