File Encryption is much more complicated.
I have no intention of doing this, although I am interested in trying it out, but just don’t have any guarantees that I will have it in a future update.
The Search capabilities is also complicated. I may be able to get the search working if the Admin searches for the entire entry, but it will never work if the Admin is searching for part of the entry.
Ex. If the Admin searches “john” it will NOT find “[email protected]”. This is due to the Encryption, but if the Admin searches “[email protected]”, then it could find the entry.
As far as time goes, I am working on getting more free time to work on the updates, but right now I am swamped with billable work. I am hoping in the next month or so.
However, here is some feedback you can give to a developer that may be able to get it working for you.
For the search I would recommend looking into the WP pre_get_posts filter. Then Encrypt the search term before the query runs.
Ex. GDS_Encryption_Class::encrypt($_GET[‘s’])
For the file encryption you are going to want to catch the file with a pre_submission filter on GForms and then run the encryption on the file content:
Ex GDS_Encryption_Class::encrypt(file_get_contents($_FILES[‘something_here’]))
Hope that helps
