A puzzle, just for fun.

Two friends, (a)lice and (b)ob are communicating through a channel encrypted with random numbers XOR'd together, like so:

keyA = randint(1024, 1024**2)
keyB = randint(1024, 1024**2)

msg = randint(1024, 1024**2)

You, an interloper, have watched all these communications, siphoning the packets as they went.

When alice sends a message to bob's mailbox, she does it like so:

mailBoxB = keyA^msg

Bob's mailbox receives the mail automatically, and applies his own key, sending it back to alice's mailbox:

mailBoxA = keyB^mailBoxB

Next, Alice's mailbox notices the message, and automatically removes her key and sends it back to bob's mailbox. All of this, the first message, the second, and the third, happens in milliseconds, the back and forth.

mailBoxB2 = mailBoxA^keyA

Finally, bob's mailbox removes his key, and deposits the now unencrypted message in his box, for him to read in the morning:

mailBoxBFinal = mailBoxB2^keyB

As as a spy, you know the first packet sent to bob, had a value of 589505.

The packet bob sent back to alice, after applying his key, has a value of 326166

The message sent *back* to bob after alice removed *her* key, had a value of:
576941

What are the values of keyA, keyB, and what is the value of the msg?

Agree or disagree: as a developer guaranteeing your work, when you accept a deposit from a client as a milestone payment, you should not spend that money until the client signs off on the milestone in case they decide your work is unsatisfactory and want to go elsewhere.

There is like a dozen shows streaming on how actual impostors imposted the shit out of people.

I never claimed to be the heir of a machine that can make art out of deposits of a single drop of blood to dozens of people on dating apps.
I never said that I can double their bitcoins by harvesting carbon monoxide and recycling plastic into endangered fauna, expanding the mind of humanity.
I never got private-jet levels of money to do something I knew to be completely impossible from the beginning.

If I ever feel like an impostor, I could honestly say that make for a very lousy one.
I guess I've got impostor syndrome squared - I feel like I'm really bad at impostor-ing, but people could be thinking that I am better at pretending to pretend to be something I actually am.

If you just want to answer my question, skip to the bottom. For those who cares, some backstory:

So...I seemed to have finally caught a break; a friend of my dad owns an IT company and also makes websites...used to. It was becoming too much for him alone so he decided to discontinue, but that's where i come in. We talked a few days ago and it sounds like I'm finally going to have a decent dev related job--even if it's only mainly websites, at least I can work from anywhere once the ball starts rolling since I'll just get direct deposits. Meaning I'd be able to visit my gf in Florida and sustain myself over there while I look to build my own client base or even get a job offer, who knows?

For you guys and gals reading this, what's your favorite/preferred static site generators and css frameworks? I know that I'll be doing mostly static sites first, and i want to deliver quality work as quick as possible. I'm cool with learning a new language once it's not too obscure; i mainly do JS and I know a bit of Python, PHP, and just the basics of Go and Ruby
