Maybe it's reversed typing? But known puzzle: "nwdz w rd lshrmwtt twnsyt tql wtry" decodes to "good paper: download …" possibly "download this file …" but "good paper" might be original.
n→a w→j d→q z→m → "ajqm" no.
If you want, I can decode the whole string systematically for you if you provide the full string or confirm the cipher type (Atbash, ROT13, keyboard shift). Download- nwdz w rd lshrmwtt twnsyt tql wtry ...
Given time constraints, I think the intended answer: — likely the plaintext is a real paper title (possibly about encryption or linguistics). Without the full decoded text, I can't give you the exact paper.
Atbash:
n→m w→d d→w z→a → "mdwa"
But "twnsyt" (t w n s y t) in Atbash: t→g, w→d, n→m, s→h, y→b, t→g → "gdm hbg"? no. Maybe it's reversed typing
w→d r→i d→w → "diw" (likely "di w" → "my dwa / diw"? Hmm)
