Could be “This is a test of the cipher system” etc. Compare length: “danlwd” (6 letters) → “solid” (5 letters) not matching. “paper” (5 letters) not matching any word length.
Without more clues, I can’t decode it fully, but the cipher looks like a or a polyalphabetic cipher with a short key like “solid” or “paper”.
“layt” → could be “that”? l→t? a→h? y→a? t→t? Not matching well. danlwd nt wy py an layt ba lynk mstqym
This looks like a cipher or code rather than a standard phrase.
“tn yw yp na tyal ab knyl myqtsm” – no English. Could be “This is a test of the cipher system” etc
Need a key. Common keys: “solid”, “paper”. Try “solid” on first word danlwd: d(3) – s(18) = (3-18 mod 26) = -15 mod26 = 11=L a(0)-o(14) = -14=12=M n(13)-l(11)=2=C l(11)-i(8)=3=D w(22)-d(3)=19=T d(3)-? key length 5, 6th letter use s again: d(3)-s(18)=11=L → LMCDTL → no.
danlwd – on QWERTY: d→s, a→s? not clear. Without more clues, I can’t decode it fully,
The text: danlwd nt wy py an layt ba lynk mstqym Words are short, and “nt” could be “is” or “not” in English, but the rest doesn’t match directly.
