Every sys/devops and programmer will know what a hash is, salt at least the sys/devops.
The general population though will be thinking of hash browns when hearing those terms and “encrypted” is absolutely close enough. So close that insisting on the difference in a non-technical context is definitely pedantic.
For reference, it’s a whole genre. Not to be confused with appliances that have speakers and bzzt or beep or play jingles or whatever, or for that matter also musical tesla coils, those are much more like speakers.
It’s been a part of computer culture since pretty much forever, now kinda dying out because nothing is mechanical any more.
