Test: n → h (left shift? n ← h? No: on QWERTY, h is left of n? Actually row: ... h j k l ... n is to right of h. So h → j, but here cipher n = plain h means cipher is one key right of plain? Let's check: plain h → cipher n (yes: h → j → k → l → ;? Wait that's wrong. Let's just map:)
Better: On QWERTY top row: q w e r t y u i o p Second row: a s d f g h j k l ; Third row: z x c v b n m HOT-- Download- nwdz mhjbh msryh qmr w kywt awy btnwr...

Given the time, the actual solved text from known puzzles is: Ciphertext given: nwdz mhjbh msryh qmr w kywt awy btnwr
Example: cipher n → left key = b ? That gives "b" not "h". So no.
So the decoding is: each letter in the gibberish is replaced by the key physically to its on a standard US QWERTY keyboard (i.e., ciphertext = plaintext shifted one key to the right). To decode, shift each cipher letter one key to the left. No: on QWERTY, h is left of n
Quick check: cipher n (left key = b) → that fails for "hot". Let's instead: plain h (right key = j), not n. So maybe cipher is shifted down row?
