Meet ROXy, a coder obsessed with being exclusively the worlds best hacker. She specializes in short cryptic hard to decipher secret codes. The below hex values for example, she did something with them to generate a secret code, can you figure out what? Your answer should start with 0x.

0xc4115 0x4cf8

ROXy is using eXclusive OR (XOR) which is a boolean operator that is widely used in cryptography. XOR compares two input bits and generates one output bit. The logic is simple. If the bits are the same, the result is 0. If the bits are different, the result is 1.

The 0x prefix in 0xc4115 and 0x4cf8 means we are dealing with hexadecimal (base16).

When you calculate XOR at http://xor.pw/ for example, you get the hexadecimal output you’re looking for. This output is used as secret code to encrypt and decrypt data which is essentially a form of symmetric cryptography.

that's a really cool one, thanks.

a little hard for me, but a fun learning experience

At first I thought it looked too good to be just a coincidence. Then I was confused. Then I read start with 0x. Then I was happy.
