We're looking to add support for encrypted files into formhub.
We get how ODK briefcase works to download encrypted forms and decrypt and
export locally.
For for submission, I see you can set a public key in xlsform. If that key

Also, what does the payload of the encrypted form to aggregate from collect
look like? I looked around but wasn't able to find documentation on that.
Thanks for the help as always,
Matt
