name: Timed AES
author: White
category: Crypto
description: |-
  I made my own AES implementation. To test its performance, I timed the encrypting and decryption operations. However, I noticed that the decryption is a lot slower than the encryption. Help me find out what is wrong.

  Wrap the flag in the uoftctf{} format.
