4096 bit keys are just too secure!

Downloaded 3 files: requirements.txt, output.txt and chall.py

Found the ciphertext and the the public key in the file output.txt.

This looked like the RSA-Chiper challenge, so I tried the decoder tool at https://www.dcode.fr/rsa-cipher

From the output.txt:

• Entered c value in Value of the Chiper message (Integer) C=
• Entered e value in Public Key E
• Entered n value in Public Key Value (integer) N

Pushed the button "Decrypt" and voilà.. flag appeared in the Results box.
