Hello,
We have an issue where the Private Key we stored was wiped out and not
backed up. The current form we have uploaded on Aggregate contains the old
Public key associated with the lost Private Key. We assume there would be
no way to recover the lost Private Key, correct?
Since we cannot continue to use the Public Key we have on our form as it
does not have a corresponding Private Key, we are thinking of uploading a
new form with a new set of keys to our Aggregate/Appspot. If we generate a
new Private/Public key set, and upload the new form (with the same title),
we will lose the old data associated with the old form (because we'll have
to delete the old form). Correct?
Is there anything we are not thinking about?
Thank you for your help

Unfortunately, you will have to just throw away all of the data collected
with the old form (whatever you hadn't already decrypted). Without the
private key, you can't decrypt it, so it's as good as worthless. And,
that's really a good thing because you wouldn't want it any other way: if
people could decrypt that data without the private key, then the encryption
really wouldn't be useful at all.
Sorry,
Chris

Chris is correct. There is no recovery if you don't have the key. If
you still have the computer that it was stored on, you can try a file
recovery app or service.
Regardless, don't throw away all the data. Back it up with ODK
Briefcase and if you end up finding or recovering the private key, you
can at least decrypt the data.
