I'm working on a web app, and one of the things it'll require is users to sign in. Here's my problem, though: I know this is going to be a fairly small app, and it's not going to generate a huge amount of traffic. I can't necessarily afford to buy secure hosting for the site. However, I was thinking of a possible workaround:

I'm not collecting anything like credit card numbers or anything else that would really need to be kept confidential. Essentially all I need from my users is a username (email address), password, and name. Now, I know how to go about storing the password in my database. I generate a random salt word, and hash the password with the random salt word in the database. To avoid secure hosting, I was thinking about using javascript to hash the password before the form is submitted. Does this alleviate the primary concern about sending the data?
