So: gsnbo qb gb zb zwoy (spacing after 5 letters).

Reverse original: blda-yt-ay-jy-lmht Atbash: yowz-bg-zb-qb-onsg thmyl-jy-ty-ay-adlb

Atbash first: "gsnbo qb gb zb zwoy" (spaces instead of hyphens). Now reverse: "yowz bz bg obnsg" . Still nonsense. So: gsnbo qb gb zb zwoy (spacing after 5 letters)

Result: "yowz - bg - zb - qb - onsg" .

Atbash on "thmyljytyayadlb" (remove hyphens first): thmyl-jy-ty-ay-adlb
