To add to Raemon’s reply: there are also browser extensions that allow you select text on the page (including input fields) and encode/decode it by selecting ‘rot13’ from the right-click context menu. In Chrome I use this one, which works fine (but I haven’t looked at the code or anything, so I can’t actually guarantee there’s nothing dodgy about it).
Why does your text show up jumbled?
Rot 13 is a way of hiding spoilers. (go to rot13.com to decode it)
