What is JotForm?
JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
As far as I understand, we do not currently have an option to encrypt current form data. We only encrypt new form entries and only when the Encrypt Form Data option is enabled.
I have sent a ticket to our development team for consideration to see if we can add the option to encrypt existing data. There is no ETA, but we will let you know if we have any updates.
