Wy Py An - Danlwd Ox Vpn Bray Andrwyd Fyltrshkn Aw Ayks

f→f (same) y→i (y→i shift -8?) not consistent. Let’s check: f→f (0), y→i (y=25, i=9, diff -16 or +10 mod26), inconsistent.

Try right shift: d → f a → s n → m l → ; (not likely) — fails. If fyltrshkn → “filtering”: danlwd Ox Vpn bray andrwyd fyltrshkn aw ayks wy py an

So Vigenère with given key not obvious. Example: awyks could be “a wyks” → “a wyks” = “a weeks” if y=e (common e→y shift in some simple ciphers). Test: awyks → a=a, w→w? no shift consistency. f→f (same) y→i (y→i shift -8

Result: pdz oig → no.
