I have a set of what I believe to be 4 (X,Y) points turned into a blob of hex

like so: 0x000080BFA8AAF340000080BF031AFE40FFFF3F41010D6741FFFF3F4153D56141

Can you decipher and explain the encoding?

  • $\begingroup$ Do you know how many X,Y points there are in there? $\endgroup$

Incredibly basic, but I get the following four points:

  • (32959, 2829775680)
  • (32959, 52100672)
  • (4294917953, 17655617)
  • (4294917953, 1406492993)

Basically, just turn each coordinate from DEC to HEX and concatenate them all after the 0x prefix. Not really a cipher, but there ya go.

Interpreting the text as 8 32-bit hexidecimal numbers, and using 2's compliment, you get:

+32959, -1465191616
+32959, +52100672
-49343, +17655617
-49343, +1406492993

I don't know if that helps.

They could be lat/long pairs, but I can't see how to convert the number raw value to a lat/long range, especially given the large values.
