You are developing an HTML5 web application that provides a discussion forum for users. When a user
registers to access the application, the user enters an email address.
Users can enter data that can result in cross-site scripting (XSS) attacks.
You need to ensure that email input is as secure as possible.
Which two techniques should you use? (Each correct answer presents a complete solution. Choose two.)

A.
Remove all nonalphanumeric characters before submitting data.

B.
Use the email tag in forms where the email address is entered.

C.
Display all email addresses inside of an HTML5 ADDRESS element.

D.
Use jQuery validation with a regular expression to ensure that email addresses are valid.

E.
Ensure that all form data is encrypted when it is submitted.

Explanation:
B: The <input type=”email”> is used for input fields that should contain an e-mail address.
Depending on browser support, the e-mail address can be automatically validated when submitted.
Some smartphones recognize the email type, and adds “.com” to the keyboard to match email input.
D: JQuery can be used to validate email addresses.
