Login + Project work flow (list, create, delete, edit a list of projects)

I need a browser-side Javascript web-app that will do the following: 1) Permit end-users to login (and optionally to permit automatically login) 2) View a list of projects available 3) Create a new project 4) Delete a project 5) Edit the settings of an existing project (title, description) 6) Page to enable/disable global settings Clarifications about functionality: The login should be done exclusively on the browser-side with no server involved. Permitted users and passwords should be defined at an external JSON file using SHA256-like hashing. I'll explain: Join the strings of username and password field for an end-user to generate a SHA256 hash. Don't worry about hacking, this is only intended as basic protection. In fact, end-users should be permitted to enable or disable the login feature from the settings page on point 6). A "project" in our context is just an item, the only thing we need to list for each project is its title and a short description about it. Other features are the basic things such as creating, removing and editing a project. The last part is opening a project, which you will later connect to another ongoing task.
