Is it possible to find out which keys were pressed on a wireless keyboard if there is equipment that intercepts the radio signal? Is it safe to enter passwords and other sensitive information through such a keyboard? How do different kits distinguish their device from others?

I’m interested in this from the user’s point of view; I'm not going to intercept someone else's signal.

Encrypted.
But this does not always help, for example www.bezpeka.com/ru/news/2009/06/17/interception-keyboard-data.html

As far as I know, Logitech and Microsoft currently use 128-bit AES encryption.

Depends more on the specific model, manufacturer and type of connection of course

I will not say anything about the specific model you indicated, but the fact is that there are a number of programs and articles on the topic of intercepting the signal of wireless keyboards. At the same time, as far as I know (but, again, I don’t say because I didn’t go deep into the topic), quite strong encryption is used in BlueTooth, so I would look towards BlueTooth keyboards (yes, they are not only for mobile phones , but also full-sized) because here we have more or less reliable encryption and, as a bonus, a free USB port if the computer has a built-in BlueTooth.
