How do I find my private key

I selected to encrypt my form and now it asks for my private key info. I have no idea what that is. Can you help?

When you enabled "Encrypt Form Data" on your form, it should have shown you the encryption wizard where you need to create a private key. You might already have created one so I suggest to check your downloads folder and look for the jotform.key file. Please refer to this guide https://www.jotform.com/help/344-Encrypted-Forms-and-How-to-Use-Them#Where-Can-I-Find-the-Private-Key-After-Downloading-It

And here's the instruction on how the data encryption was enabled on your form and how to create a private key file https://www.jotform.com/help/344-Encrypted-Forms-and-How-to-Use-Them#How-Can-I-Enable-Form-Encryption.
