Just an example. This is really not an obstacle.

Pyinstaller has now a new and approach which is simpler and safer to use.
They have removed old and troublesome Cryptodome.
Use now tinyaes which use ASE 256.
If need it.

pip install pyinstaller[encryption]

Then just use --key parameter on command line.

The other question is: is it really worth it? What's the risk if you don't prevent people doing that?

the risk is that the program can be shared to unauthorized person if not bind to a specific computer

That's true, but I pointed to pyarmor because it allows to bind the obfuscated script to specific machine

Sorry, I didn't see you quote the reverse engineering link. Still keep in mind

Please note that it is still very easy to extract the key and get back the original bytecode, but it should prevent most forms of “casual” tampering.

30 years ago licensed programs sometimes worked with "dongles".
You can still do that because every USB stick has an unique serial,
that you can use as a dongle. Cost = price of a small USB.

It's difficult to counterfeit, especially if you don't know
which serials are valid.

And you don't need to know the customer's HHD serial.
