Most of us have seen FaceBook and Twitter have a login form on their homepage; facebook also have the registration form.
As far as I know the way to secure any kind of sensitive data is through the use of a SSL. Apparently FB and TW dont have any on their home page.
I found some options of using jquery, javascript etc. But I dont find it much useful since JS can be disabled by some users.
My question is, is it possible to secure data transmission without using SSL?
