And you can see the power trace change drastically, as below:

Finally, let's flip another bit. Change the input plaintext as follows, such that bit #4 in the final bit is set HIGH. We can plot the two power traces on top of each other, and you see that they are differing at a specific point in time:

Walking back from the right, you can see this almost directly matches bit numbering for those last two bytes:

With a bit of setup done, we can now perform a few captures.
