In a bit of a pickle with deciphering...

So, I was just doing this online quiz about cyber security and all was going fine until the last question: These two numbers: 0xB105F00D and 0x4BCB0EE0 can be used to generate a secret key starting with '0x', what is it? I tried adding, subtracting, reversing, swapping binary 0s with 1s and many combinations of these but still I didn't get anything that even looked correct. Is there anything I am missing out? Seriously, this forum is my last resort and I literally tried everything I can think of.

Btw, this aint homework or anything like that, I'm just doing it in my spare time.

Is it a multiple choice question? The first one looks like hexspeak lol

 

[zaka100]

Nah, its not. I'm just totally baffled by this question. Its actually from a government scheme called 'cyberdiscovery' and is this question is aimed at under 18s which is kinda crazy

 

[iParanormalx]

I have a hunch they've designed the question to be overthought. I think the answer is electricity, bits, bytes, or something fundamental like that. Those things are FOOD for the B10S lol

 

[zaka100]

Maybe. I mean, what other simple ways can I manipulate these numbers?

To point you in the right direction, you have to find a way to combine them so that the last 4 digits read "FEED".
Hint: you'll also need to convert it to binary first:

1011 0001 0000 0101 1111 0000 0000 1101
0100 1011 1100 1011 0000 1110 1110 0000

Adding them in hex you get FEED as the last 4

*except that one lucky coincidence with the word that it works with addition, the first part doesn't though.
If you wanna know though

Wow, damn how did u think of that lol, I know I would have never. Yeah, I did get to the conclusion that the second half of the code was 'FEED' but I had no idea what the first half was. At some point, I was even assuming that the hex number would translate to something in ASCII but it didn't
