BruXOR

The main idea finding the flag is XOR Bruteforce.

Step-1:

After reading the message in the question,

There is a technique called bruteforce. Message: q{vpln'bH_varHuebcrqxetrHOXEj No key! Just brute .. brute .. brute ... :D

The first thing I searched online was XOR Bruteforce and I got some helpful results.

Step-2:

I followed the URL: https://www.dcode.fr/xor-cipher

Since in the message, it is clearly that there is no key, my inputs were as follows: (Only Bruteforce xP)

Step-3:

After decrypting, we get the following results, amidst which I found the flag.

Step-4:

Finally the flag becomes: flag{y0u_Have_bruteforce_XOR}
