    I was bored again and I fancied creating something useful to easily convert between entities etc. I was inspired by Mario's excellent encoding tool, which I really like but I wanted to be able to convert to unicode and use multiple strings at once. So I give you....

    Hackvertor!! which will allow you to use placeholders to convert a string of text. The idea is you provide some input like "{concat}alert(1){/concat}" for example and then the script will convert it into a string concatenation attack.

    Update...

    I've added loads of new options, find and replace, dom object view, text selection, eval generation, clear, test code and finally send the output to a URL.

    Check it out:- Hackvertor
