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.
