Encrypting and signing it before sending it assures the receiver that
its contents were not disclosed in transit and that the contents of
the file were not modified while moving across a network controlled by
other, possibly hostile, parties.

Whether that is part of the David's security team's requirements, I
cannot say.

Does that make sense?  I may not be explaining very well.
