It wouldn't work that way. You have to split your file into multiple
files and iterate over them with GPG. Or, if this is applicable,
concatenate all webform input data before encryption and store it in a
single DB field (this is how I would implement that: since all data is
already encrypted, is there a reason to store it in many different fields?).
