thmyl → sglxk (no). Need key — but kn2000 suggests kn might be part of known ? Actually alkybwrd — looks like alkybwrd if shift -3 from cipher:
thmyl → g s n b o? Let's do systematically: t (20) ↔ g (7) h (8) ↔ s (19) m (13) ↔ n (14) y (25) ↔ b (2) l (12) ↔ o (15) So thmyl → gsnbo (not English). thmyl brnamj zf awrj ly alkybwrd kn2000
Wait, if ly = in , then l→i (-3), y→n (-3) consistent! Yes! Because y (25) -3 = 22 = w? No — 25-3=22→w, not n. So not consistent. So ly can't be in with a fixed Caesar shift. thmyl → sglxk (no)
Better: Let’s actually decode ly assuming l → i and y → n . l (12) to i (9) = -3 y (25) to n (14) = -11? That’s inconsistent unless it’s not a Caesar shift. Let's do systematically: t (20) ↔ g (7)
