obamg gbh bjzodq → no. Try ROT5 on group1: tnzyl → y s e d q? No.
tnzyl → gma b o (g,m,a,b,o) syt → h b g jwlaqy → q d o z j b
Better to run Atbash on each letter without changing order , ignoring hyphens: tnzyl-syt-jwlaqy
tnzyl → lyznt syt → tys jwlaqy → yqalwj
Full ROT13: (still not English). 4. Try reverse string + ROT13 or Atbash Reverse: yqalwj-tys-lznyt obamg gbh bjzodq → no
Shift right instead: t→y, n→m, z→/ (no), so maybe not. If this came from a puzzle or game, a common key might be "key", "cipher", or a name. Without a key, Vigenère is hard to brute manually. 7. Hypothesis: it’s already a plaintext but obfuscated Could be a username, code, or random test string. Try reading each group backwards:
Atbash result: gmabo hbg qdozjb → not readable. ROT13: a↔n, b↔o, etc. tnzyl → gma b o (g,m,a,b,o) syt →
t (19) +13 = 32 → 32-26=6 → g n (13) +13 = 26 → 26-26=0 → a (but careful: a=1? Let's use a=0,b=1: t=19, +13=32%26=6→g; n=13,+13=26%26=0→a; z=25,+13=38%26=12→m; y=24,+13=37%26=11→l; l=11,+13=24→y) – let’s do systematically:
t(20th letter? Better use a=1,b=2: t=20, +13=33, 33-26=7→g; n=14,+13=27-26=1→a; z=26,+13=39-26=13→m; y=25,+13=38-26=12→l; l=12,+13=25→y → "gamly")
