Thmyl Brnamj Zf Awrj Ly Alkybwrd Kn2000 -

t↔g h↔s m↔n y↔b l↔o → gsnbo

But check alkybwrd → could be alkybwrd = something ?

But maybe ? (a↔z, b↔y, etc.) ly → ob (not "in"), so no. Step 3: Try ROT13 (common for obfuscation) thmyl brnamj zf awrj ly alkybwrd kn2000

Better: Try ROT13 on whole phrase:

If ciphertext letter → plaintext letter by shifting (Caesar cipher with key 3, decode by shifting left 3): t↔g h↔s m↔n y↔b l↔o → gsnbo But

Given the time, if I try a on the whole text: thmyl → oc hg ? Let's do properly:

But note: kn2000 might mean the key is ? Or it's a citation? Step 3: Try ROT13 (common for obfuscation) Better:

So decryption: cipher -3:

Wait, if ly = in , then l→i (-3), y→n (-3) consistent! Yes! Because y (25) -3 = 22 = w? No — 25-3=22→w, not n. So not consistent. So ly can't be in with a fixed Caesar shift.
