Are Enter Keys Coded Differently using Linux?

0 votes
51 views

I have both an Enter key in my keyboard and another marked "Enter" to the right of the keypad.

Recently, I created a passphrase that was input by pressing the far-right Enter key, which seems to require me to input the passprase with the far-right Enter key.

This has me wondering. Are the two keys encoded differently?

I'm pretty sure the keys are wired differently in the keyboard, but the question is what happens between the electronics and the passphrase software... there may be a layer somewhere that declares them similar. Then again, you want as little layers as possible for passphrase code in order to make it more secure.

There is a command line program "showkey" that will show what key is pressed. The X11 equivalent is "xev". I can't try them here b/c I only have access to Redhat via ssh at the moment.

In any case, I'm pretty sure it's not a good idea to have a key like that in your passphrase. What if your keyboard breaks and your new keyboard does not have the same key? Better to use the normal exotics
~!@#$%^&*()_+ etc.
