Hello, in my course had a joke, who could decipher the code would win a prize, I tried in hexadecimal, but I did not get anything.

51 44 52 20 59 44 20 57 44 52 20 4a 48
51 57 4c 4f 50 48 51 57 48 20 51 48 56
56 44 20 45 52 44 20 51 52 4c 57 58 20
48 56 46 58 55 44 55 44 4c 59 44 20 46
52 51 57 55 44 20 44 20 50 52 55 57 48
20 47 44 20 4f 58 43 20 54 58 20 49 58
4f 4a 58 55 44

Note: I know this doesn’t have much to do with programming, but I would really appreciate your help in this.

Obs²: I won’t even participate in the game, I’m just really curious.

Just like you, I saw that it was a hexadecimal code. I then converted the data to ASCII table values here. Giving me that result:

"QDR YD WDR JHQWLOPHQWH QHVVD ERD QRLWX HVFXUDUDLYD FRQWUD D PRUWH GD OXC TX IXOJXUD"

After receiving this result, I thought it looked like a code generated by cypher of Caesar. So I went on a online tool of Brut force and put the result of the previous step, which brought a satisfactory result (with the shift of +3 in the original message):

"NAO VA TAO GENTILMENTE NESSA BOA NOITU ESCURARAIVA CONTRA A MORTE DA LUZ QU FULGURA"

OBS: It is possible that some error occurred during some of the conversions, because it was done in tools that I have not tested before. But the essence of the message is this and the process to be done is this.

  • I even thought of Caesar’s cipher, but I couldn’t find a tool to do Caesar’s cipher.

That is hexadicimal yes

Translation is this

QDR YD WDR JH
QWLOPHQWH QHV
VD ERD QRLWX
HVFXUDUDLYD F
RQWUD D PRUWH
 GD OXC TX IX
OJXUD

Now all that’s missing is the mathematical function that untangles it

Our friend even found a translation, but it must be some ciphertext command code.
