Let me try to decode – the word Lite and Vpn suggest it’s meant to be readable as English after decryption.
Given your mention “good piece” – maybe you are just saying this scrambled phrase is a good example of lightweight VPN security or a test cipher.
So maybe it's not a Caesar shift but a keyboard shift or a simple substitution. But "Lite Vpn" are plain English. So the rest may be anagrams or code.
Given “Lite” is likely “Lite” in plaintext, then no shift for that word. So maybe only words are shifted. But "Vpn" → likely "Vpn" plaintext? Then no shift.
It looks like you're referencing a phrase in a likely coded or ciphered form (possibly a simple shift cipher, like a Caesar cipher).
But if "Lite Vpn" is a clue – maybe it's – then the phrase is: "danlwd fyltr shkn layt" could be a slogan: "download filter shaken late" ?? Doesn’t fit.
If I treat "danlwd" as an anagram: "danlwd" → "dwaln" no. "fyltr" → "flytr" close to "flyer"? "shkn" → "shkn" maybe "shunk"? "layt" → "late" (likely). "swrty" → "wrsty" no, maybe "strawy"?
