wp_explain_nonce() WordPress Function

This function was introduced in WordPress 2.0.3 and is used to help explain what a nonce is and why it's important. A nonce is a "number used once" and is a security measure to help protect against certain types of attacks. When a form is submitted, the nonce is checked to make sure that it's a valid request. If it's not a valid request, the form submission is rejected.
