A number of years ago, the FCC started allowing digital emissions under
Part 97.309(b). 
No doubt to "advance the radio art."

They have to use a readily available encryption key or code. 
Which is probably what that guy meant.


Funny thing. About 20+ years ago, the two radio techs for the FB1 were
both amateurs and regularly used two-meters in the evening to discuss
what they were doing with their employer's system. You could learn a lot,
listening to those guys.

(b) Where authorized by §§ 97.305(c) and 97.307(f), a station may
transmit a
RTTY or data emission using an unspecified digital code, except to a
station
in a country with which the United States does not have an agreement
permitting the code to be used.
RTTY and data emissions using unspecified digital codes must not be
transmitted for the purpose of obscuring the meaning of any
communication.
When deemed necessary by a Regional Director to assure compliance
with the FCC Rules, a station must: 
(1) Cease the transmission using the unspecified digital code;
(2) Restrict transmissions of any digital code to the extent instructed;
(3) Maintain a record, convertible to the original information, of all
digital
communications transmitted
