Encryption key: what format the private key takes?

Hi there,I have an encrypted form that I setup yonks ago. I've just tried to view a submission and I am getting a 'Upload Your Private Key' message (see attached). I've viewed a few threads that says check your downloads folder etc but it was ages ago so it won't be there. I'm sure I would have saved it so I was wondering what format the private key takes? As then I can search for it. Thanks 

Hi,

Thank you for contacting Support.

The default filename of the key is jotform.key, if you used the form builder to generate the key, from here:

I believe it's an RSA-2048 private key, PKCS#8 format, if that's what you mean by format.

If you have lost the private key, then there is not much that you can do. It means that your encrypted data is lost forever, there is no copy of the same on our servers and it is not possible to crack the one that you had.

You may refer to our "Encrypted Forms and How to Use Them" guide for more related information.

Let us know if you have any questions or if you need further assistance.

Thank you for the comprehensive reply - that's useful. I still can't find the key but at least I know what to look for. cheers
