Secure PHP Webpages

I would like a few secure webpages with the following functions: <strike>Secure Login Page: </strike> <strike> -Username (Text Field) -Password (Text Field private e.g. replace characters with *) -Login (Button) Notes: Database already exists and is used by my vBulletin forum, so this needs to check the username + password hash to validate. Forumla is md5(md5($pass).$salt).</strike> Edit: I have created the login page myself which took me an hour with absolutely bare minimal php knowledge... The rest of the work should take 2-3 hours tops for someone who knows what they are doing. Home Page: -Add New License (Button) -Reset HWID (Button) Add New License Page: -Email (Text Field) -License Key (Text Field) (License Key is 19 characters long e.g. 4FS7-R9CD-A9RW-2KDD) -HWID (Text Field) -Add License (Button) Notes: When adding a license, the Email and License key is checked via the following site: [login to view URL] First the license is validated, and if it is valid it is then activated via the same site. The product ID will always be 55264. If the License is successfully validated and activated, the data received is added to a local MySQL database. Reset HWID Page: -Email (Text Field) -License Key (Text Field) (License Key is 19 characters long e.g. 4FS7-R9CD-A9RW-2KDD) -New HWID (Text Field) Notes: Reset HWID first checks the local MySQL database if the email and key exist, then we check a text date field in the local database to check if a reset is allowed (resets can be done once per 7 days, and the text date field is set to (current date + 7 days) each time a HWID reset occurs. If the current date is not on or after the next available reset date then the Reset HWID page will not be allowed, and a message displayed telling the user the date at which they are allowed to reset. No images are necessary, I just want black background with lime text & lines, and must look neat and tidy.
