Hi,
Prior to explaining each specific issue you raised. It should be important to note the following introductory note about encryption. Encrypted forms work by encrypting the data on the phone the moment it is saved. Data sent to KoBoToolbox is encrypted and completely inaccessible to anyone not possessing the private key. In this case, KoBoToolbox serves simply as a storage locker for your encrypted files - a place to upload and then download for later for local decryption (using ODK Briefcase). Since the form submissions are encrypted, it means, however, anything that requires access to the data like the map view or data export won’t work within KoBoToolbox. The extra level of security makes using KoBoToolbox in a way to collect sensitive data while meeting certain data protection protocols possible. (source)
At send
Yes, since the form while on the phone and not yet submitted, remains open for editing on the phone.
Yes as long as they are using the interviewer phone. Same logic as above applies
Yes it restricts it because the server will not have the necessary decryption code needed to decrypt the data for processing. @jnm can confirm this too.
You must be able to export your data using decryption services which means some of the benefits of exportation would be lost. My suggestion would be you keep a copy of your project that is not encrypted yet has no data to allow you to export the SPSS values and use them on the data that you will eventually collect.
The answer should be yes for this. However you should try this and see if there is a challenge
There are always pros and cons for various features including encryption. Unfortunately we cannot exhaust all the seen and unforeseen limitations. We rely on users to share their experiences which we can document for other users as they go.
