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.
Once the encryption is enabled, the public key is saved at JotForm, and private key (usually named jotform.key) is supposed to be downloaded by the form owner. The private key is required for decryption.
Unfortunately, there is no way to decrypt the data if the private key is missing (lost or was not downloaded).
If you do not have the private key, you might consider generating a new key pair by disabling and enabling the form encryption option. Note, that this will not decrypt the old data.
