How to pass Social Security Nubers from jotform submissions over email in a secure way?

Hi, I currently have a form here : http://hawkwebdesign.net/penta/employment.html If you click on

"Click Here to fill out the application" you will see the form I have created. In this form we have the ability to take social security numbers. I have bought a SSL from my hosting company but my question still remains: When this info is sent to my clients, is this still secure? If not, how can we secure it to their end?

Any help would be appreciated.

I would first like to let you know that per our terms of use you can not request Social Security Number directly on the jotform itself.

Here is the excerpt of interest:

Phishing You agree that Company may terminate your JotForm Service immediately if a form is created or JotForm is found to be used to: Obtain credit cards sensitive information, get social security numbers, show content with child pornography. Or if a form was made to steal user login credentials. All these activities are considered as Phishing and any account along with the guilty forms will be suspended immediately

Even though your forms or account does not get disabled right away as you make it, our system will disable it (form and account) if such fields are found.

I would suggest removing that field and having your clients either ask this info over phone or over email, or alternatively have that field on some other page for people filling out the jotform to be redirected to.

Do let us know if you have any questions and we would be happy to answer them.
