Sbwnj Bwb Hlqt Alwhsh -

Right shift: s→d b→n w→e n→m j→k → dnemk — no. Given the time, a plausible guess: is most common. Let me reverse ROT13 your ciphertext: Applying ROT13 to sbwnj bwb hlqt alwhsh : s→f, b→o, w→j, n→a, j→w → “fojaw” — no. But whole thing: sbwnj → foja w? Wait, I did wrong.

Applying to sbwnj : s → h b → y w → d n → m j → q sbwnj → hydmq (not obviously English) sbwnj bwb hlqt alwhsh

It looks like you've shared a phrase that appears to be encoded or written in a cipher: Right shift: s→d b→n w→e n→m j→k → dnemk — no
