It takes one

A target believed that encrypting their data twice using the same weak key would provide enhanced security against brute-force attacks. You have been tasked with demonstrating that this naive cryptographic implementation fails to increase the effective keyspace.

OBJECTIVE

Exploit the cryptographic flaw of repeated encryption with a single weak key, develop a script to brute-force the limited keyspace, and automate the decryption process to recover the plaintext flag.
