So: bshqe gshs - - qhb 4 — not English.
h(8) +5 = 13 → m y(25)+5=30→4? out of range — wrap: 30-26=4 → e n(14)+5=19 → t w(23)+5=28→2 → c k(11)+5=16 → q → mte cq ? no.
But note hynwk → shift back by 1 gave gxmvj — maybe it’s a name? Let’s try (equiv forward by 5): h=7-21=-14+26=12→m y=24-21=3→d n=13-21=-8+26=18→s w=22-21=1→b k=10-21=-11+26=15→p → mdsbp no. hynwk myny - -wnh 4
Try : h(8)-11=-3+26=23→x y(25)-11=14→o n(14)-11=3→d w(23)-11=12→m k(11)-11=0→? z (using a=1? no, a=0) better to map a=0 to z=25. Let’s redo properly: a=0,b=1,…,z=25.
Since the example is short, a likely plaintext could be: Shift : So: bshqe gshs - - qhb 4 — not English
Shift (a→f, etc.):
Given the format "hynwk myny - -wnh 4" — maybe the is: "Automatic Caesar cipher detection and decoding for shift values 1–25" The app would take such a string, try all shifts, detect English words by dictionary, and display the most likely plaintext. Let’s redo properly: a=0
Try backward by 5: h=7-5=2→c y=24-5=19→t n=13-5=8→i w=22-5=17→r k=10-5=5→f → citrf not word.
