Sudarshan Categories Computers Databases. The login page could allow the user to provide a user name and password. The servlet corresponding to the login page could verify that the password matches the user; for example, by using the user name to retrieve the password from the database and checking if the password entered matches the stored password.
Instead, a hashing function is applied to the password, and the result is stored in the database; even if someone sees the hashing result stored in the database, it is very hard to infer what was the original password. The same hashing function is applied to the user-supplied password, and the result is compared with the stored hashing result. Thus, the password relation would have the schema user password user, salt, passwordhash , where passwordhash is generated by hash append password,salt.
Encryption is described in more detail in Section 9. For example, after the user is authenticated and the session object has been created, the login servlet could store the user-id of the user as a session parameter by executing the method session. If the request was part of an ongoing session, the browser would have returned the cookie value, and the corresponding session object would be returned by getSession.
The servlet could then retrieve session parameters such as user-id from the session object by executing the method session. If the attribute userid is not set, the function would return a null value, which would indicate that the client user has not been authenticated.
Consider the line in the servlet code in Figure 9. The following code implements this check; if the user is not logged in, it sends an error message, and after a gap of 5 seconds, redirects the user to the login page. For customers who have standardized on Oracle, this eliminates extra steps in installing or moving a Hue deployment on Oracle.
