Short XOR


The XOR operation sees great use in the unconditionally secure One-time pad encryption technique. If used improperly, however, it can be quite weak.

Given this plaintext: BWDxEl]mNw]v40]pi3pw^Qgsd7vjod]h2zq~

Can you find the short, repeated key and get the flag?

If you're not sure what that means, take a look at the example of the Wiki page for XOR ciphers and remember that the flag starts with CTF{ and ends with }.
