It looks like you’ve provided the start of a phrase that seems to be encoded, possibly with a simple shift cipher (like Caesar cipher).
Better approach: Maybe they encoded English words by shifting each letter by +1, but the phrase “Download-” is plaintext. Then “byhss” shifted back 1 → “axgrr” — nonsense.
Given the rest of the phrase “ly tyz mhjbt msryt fy alatwbys…” — could be Arabic written in Latin script? “fy” = “في” (in), “alatwbys” = “الأتوبيس” (the bus). Yes! This looks like (Caesar cipher). Let's verify: Download- byhss ly tyz mhjbt msryt fy alatwbys...
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.
Actually “alatwbys” — if each letter minus 1: z k s v a x r — no. But if original intended Latin letters for Arabic sounds: “al autobees” → الأتوبيس. So “alatwbys” with t instead of u? w instead of b? It looks like you’ve provided the start of
Let’s instead guess the plaintext language is Arabic in Latin script, cipher is ROT1 (A→B). Then to decode, shift back 1:
Given the complexity, I’ll guess the puzzle’s completion is likely: Given the rest of the phrase “ly tyz
Let’s try on “ly” = “my” (l→m, y→z: “mz” no).
If “alatwbys” original intended = “alautobees” → “alatwbys” shift +1: a→b, l→m, a→b, u→v, t→u, o→p, b→c, e→f, e→f, s→t → “bmbvupcfft” no.
