Lab: Mycrypt Functionality

Create a website that does these things:

script 1--- index.html -------------------------

• create an html form with 3 text boxes, a textarea, and a submit button to get the following info:
  
  
• textbox 1 - firstname
• textbox 2 - passphrase
• textbox 3 - email address
• textarea - at least 5 lines of 'good advice'
  
  
• pressing submit sents the form data to senddata.php.

---------------------------------------

script 2 --- senddata.php ------------------------------

• encrypts the data using the passphrase as a "key"
• writes the encrypted data to a textfile called "info.txt"
• emails "info.txt" as an attachment to the specified e-mail
• prints a notice to the user that the e-mail was sent
• shows a link to "decrypteddata.html" using this format:
  
  
• $myaddress = "http://".$_SERVER['SERVER_NAME'].":".$_SERVER['$_SERVER_PORT'].
  "/".basename(dirname(_FILE_))."/decrypt.html";

----------------------------------------------------------

script 3 --- decryptdata.html -----------------------------

• has a form asking the user for their passphrase in a textbox
• form action: "./decryptdata.php"

----------------------------------------------------------

script 4 --- decryptdata.php ----------------------------

• opens the file "info.txt"
• decrypts the data using the passphrase send from decryptdata.html
