>The 3.5mm jack outputs the regular audio data. You could just make it output encrypted data, but that is the same as removing it, all the headphones won't work.

The 3.5mm jack outputs an analog signal. It's already been converted from digital data to an analog signal by the phone's DAC chip.

but hypothetically you could send a digital encrypted signal over the audio 3.5mm jack, provided that the receiving device has an ADC and can decrypt.

There are a lot of ridiculous things going on every day in many areas of life that are there just because someone wants to make a buck.

All of DRM sounds (and actually is) ridiculous.
