I use it to encrypt some sensitive data that i need only for few people at my organization! It's very easy use if you know how php works :). Some features like auto-loading could be improved but they are still not yet in version 1 so thats the reason why its free!! If You guys think about upgrade maybe do it sooner than later because there will probably come new updates soon ;) Maybe even more new encryption options too :) Its worth trying out as an alternative way of storing secret information! I like the way that Ultimate PHP Encoder works. It's easy to use and the customer support is top notch. I have never run into a problem that I couldn't solve. I wish that it was a little bit more expensive. There is a very good chance that you will run into an issue that you can't solve. But with customer support, they will always be there to help you. I am encoding PHP code for a variety of different websites. It has allowed me to be able to have one code base for all of my websites.
