Try backward by 1: h=7-1=6→g y=24-1=23→x n=13-1=12→m w=22-1=21→v k=10-1=9→j m=12-1=11→l y=24-1=23→x n=13-1=12→m y=24-1=23→x w=22-1=21→v n=13-1=12→m h=7-1=6→g → gxmvj lxmx - - vmg 4 — not English. 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. h=7, y=24, n=13, w=22, k=10, space, m=12, y=24,
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. z (using a=1
But I notice: hynwk → try shift forward by 11: h+11=18→s, y+11=35 mod26=9→j, n+11=24→y, w+11=33 mod26=7→h, k+11=21→v → sjy hv no.
Given the string "hynwk myny - -wnh 4" , it looks like a shifted cipher (likely a Caesar cipher) where each letter is replaced by another a fixed number of positions backward or forward in the alphabet.
Better try systematic backward shift until English appears.
