That was fun!

Easy to solve with Python code

The ^ operator in Python represents the bitwise XOR operation. When applied to two numbers, it performs the XOR operation on each corresponding pair of bits. Here's how it works:

0xc4115 -> 11000001000100010101 (binary)

0x4cf8 -> 0100110011111000 (binary)

XOR ( ^ )

Result -> 10001101111010010101 (binary)

When you use the hex() function to print the result in hexadecimal format, it converts the binary result to its hexadecimal representation:

10001101111010010101 (binary) -> The Flag (hexadecimal)

So, print(hex(0xc4115 ^ 0x4cf8)) will output The Flag.

really tricky , but i like it .

The actual given code doesn't have CTFLEARN in it, it does begin with 0x. For the love of god, don't think it needed to have CTFLEARN and search for it using the answer for 10 minutes like I did. Godspeed, friends.

start with '0x' and followed by the scode

Likely the best when we start cryptography,refer to xor calculation to decode secret

Means? can you explain?

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.

the webpage also strips the "0x" from the begining both inputs and outputs..

Hard for beginner)

Clue for the newbies: Focus on the name ROXy

For the newbs. Here's a hint. ROX is a reverse of XOR. you got 2 hex strings. Know what to do?

so sorry about leaking it.!! UGhhh forgive me I thought it was a protected comment. They need to have a check mark or something in the box to let you know if it's been selected or not

Nice one ROXy, liked it

guys the flag does contain CTFlearn{...} , don't get confused!
