It's an exercise: the description contains all the information you need (including the algorithm) to decode the file.

You aren't supposed to guess: you are supposed to use a brute force attack approach to decrypt, which isn't hard or too time consuming given that the key you are looking for is three lower case characters - i.e. has only 26 * 26 * 26 possible combinations and the decryption result is text using only English words.

Give it a try, and see how far you can get...

Blame yourself, because:
You lock the door
And throw away the key
There's someone in my head but it's not me.

Part of me agrees with you. :-)

Solution 3

It's you job to come up with the algorithm, not beg for it.

All I'm going to tell you is that the resulting text is going to contain the word " the " and that you're going to need loops within loops to solve it.
