There’s an authorization code for some Thyrin Labs information here, along with someone’s favorite song. But it’s been encrypted! Find the authorization code. encrypted.txt
Hint: You may want to look at what the relative frequencies of letters in english text are.
The hint said the frequencies of letters in english. So, the first time I saw the encrypted text is 3 characters at the first sentence. Guess what? That must be “The” word. Mark those 3.
And then look at other word that seems familiar. For example, 4 characters word that have T, H and E such as “THEY” and so on.
After figuring out one by one of the substitution cipher. I got the result like this:
THE AUTHORIZATION CODE IS ILLMAKEAMANOUTOFYOULETS
Maybe I got the flag 😉
