This is an all-in-one solution designed to automate various block cipher (e.g. AES) challenges typically encountered in Capture The Flag (CTF) competitions.
It has the following features:
- Detect Block Cipher Mode used
- Detect Padding Method
- Detect IV Reuse
- Detect Block Size
- Attack using common attacks (e.g. Chosen Plaintext or Padding Oracle)
- Easily extendible
A file similar to main.py must be created. init_server and encrypt must be implemented.
This method must return an object/process/handle that can be used to encrypt/decrypt data.
This method must be implemented such that it uses the process returned from init_server and encrypts it. It must return a hex string that is the result of the encryption.
This method is not necessary to be implemented, unless you're running a Padding Oracle attack.
After these methods have been implemented, you start the detector by running begin() on the newly created instance of BCDetector
