If you're going to post this sort of shit, you could at least attempt to explain the steps.

I'm with you up until you convert the keys for hat and quit back to hex. I don't understand what you mean by applying substitution at that step, or where the strings:

73746179

6c6f76

Are coming from. At the end result, it appears you've re-encrypted the message to decrypt as the desired output after changing those 2 words. But does that help decrypt the original message somehow if you don't know it already?

6c6f76 = lov

73746179 = stay

if yuoure like "wow thats so easy", then it is. its just a simple xor stream cipher. its garbage.


theres all kinds of attacks on it. I think the hardest to brute force is about a week. WEP keys (wifi) use it, and can be cracked in seconds.

I think it's great that even someone with your obvious disadvantages is still able to find a job. Show 'em you're a tiger, Tiger.
