So maybe not ROT13. "Zero Dark Thirty" is plain English. The rest seem scrambled. Could be: "danlwd fylm" → "watch movie"?
ROT13 of "danlwd": d→q a→n n→a l→y w→j d→q → "qnayjq" — not English.
So: ? Redundant. Given typical internet cipher puzzles, it might be ROT-5 or a simple keyboard shift (each letter shifted to a neighbor on QWERTY). danlwd fylm Zero Dark Thirty ba zyrnwys chsbydh
This looks like a rather than a language.
Test: d→w (+21 or -5 in alphabet) a→a (no shift?) n→t (+6) l→c (-9) — inconsistent. ? "danlwd" could be Welsh? But "fylm" looks like "film" in Welsh is ffilm . "ba" might be Welsh for "if" or "go". "zyrnwys" — looks too long for a common word. "chsbydh" — might be a name. So maybe not ROT13
But "fylm" → "film" if you swap y→i and l unchanged, m→m — that’s a clue: y→i in Caesar? y (25) to i (9) is a shift of +10 mod 26? Not consistent. Given the pattern, the most plausible is that → "watch film" or "view film" if each word is shifted by a fixed number. Let’s brute-force guess: If "danlwd" is "watch": d(4) to w(23) = shift +19 or -7. a(1) to a(1) shift 0 — not consistent. So not a single Caesar. Given the time, I suspect the intended solution is that this is Welsh or Cornish (Brythonic language) with "Zero Dark Thirty" inserted as English. But if it’s a puzzle: "danlwd fylm" could be "watch film" if read backwards and letter-substituted. Quick possible answer: danlwd fylm → watch film ba → of or and zyrnwys → Zero Dark Thirty scrambled? chsbydh → movie scrambled.
ROT13 of "fylm": f→s, y→l, l→y, m→z → "slyz" — not English. Could be: "danlwd fylm" → "watch movie"
Let’s try : "danlwd" → w z m o d w → "wzmodw" — not English. Maybe it's not Atbash. 3. Try Caesar shift (ROT) Common shifts: ROT13 (a↔n)
Given the symmetry, I’d guess the plaintext is: (or similar).
Let me break it down:
But the phrase includes English "Zero Dark Thirty" so likely not full Welsh. ? No clear pattern yet. 7. Try reverse each word "danlwd" reversed → "dwlnad" — nonsense. "fylm" reversed → "mlyf" — not English. "ba" reversed → "ab" — maybe "ab" as in abbreviation. "zyrnwys" reversed → "sywnryz" — no. "chsbydh" reversed → "hdybshc" — no. 8. Try swapping pairs or anagram "danlwd" could be an anagram of "landwd" — "landwd" no. "danlwd" letters: d,a,n,l,w,d → maybe "dandwl" no.
