I made the following changes:

1) I added links to the footer
2)Made changes to the CSS file for the footer
3) I created a dashboard.jsp page
4) I created a images folder with images of cars
test commit
1.added the getNewSalt() feature that generates a secure, random salt.
2.added the method that hashes the password+salt and returns hash:salt
 in sha1-256.
 Researching this i found out that sha1-256 is not very secure and we
could easily implement PBKDF2 algorithm when we are trying to make it
more secure.
 I tested this program in isolation and it works as designed.
added a few comments.
