But if it’s a Caesar shift of -1 for whole phrase: b→a, y→x, h→g, s→r, s→r → “axgrr” — not matching.

Let’s test Atbash on “byhss”: b (2nd letter) ↔ y (25th) y (25th) ↔ b (2nd) h (8th) ↔ s (19th) s (19th) ↔ h (8th) s (19th) ↔ h (8th) Result: “ybshh” — not a word.

decodes (with shift -1) to: “Download- axgrr kx sya lgias lrqxh ex zksvaxr” — not readable.

“byhss” → axgrr? No. Maybe ROT3? b→y, y→v, h→e, s→p, s→p → “yvepp” no.

Let’s try on “ly” = “my” (l→m, y→z: “mz” no).
