# CryptoHack Requester Package
This is a simple python package to ease interaction with CryptoHack's challenges over Netcat and Web API.
## Installing / Getting started
The project has been tested with python >= 3.6.9. It may works with previous version, but nothing sure.
To install the package simply use `pip`:
```shell
python3 -m pip install CHRequester
```
## Features
CryptoHack has some challenges working with a Web API ([Block Cipher Mode challenges](https://cryptohack.org/challenges/aes/)), and some through server comunication. They generaly need automation so it is recommanded in the [FAQ](https://cryptohack.org/faq/) to use the [Requets](https://requests.readthedocs.io/en/master/) package for web challenges and [Pwntools](http://docs.pwntools.com/en/stable/) to communicate to a challenge on a server.
This package offer a more user-firendly and less time-consuming way to communicate with these challenges.
### Example of usage with the Web API:
```python
from ch_requester import URLRequester
if __name__ == "__main__":
BASE_URL = "http://aes.cryptohack.org/oh_snap/"
R = URLRequester(BASE_URL)
# adding actions to the requester
# first give the name of the action
# then specify a tuple of inputs that are needed for this action
# then specify a tuple of outputs that can given in return
# 'error' can be specified as an output if the challenge returns
# useful information through an error message
# else, an Exception will be raised if an error is returned
# and the user does not specify it as a desired output.
# inputs must be in the order of the url, e.g.
# http://aes.cryptohack.org/oh_snap/ciphertext/nonce/
R.add_action('send_cmd', ('ciphertext', 'nonce'), ('msg', 'error'))
# we can then execute an action, by giving its name as first parameters.
# The following ordered arguments are the wanted outputs from this action.
# Even if we specified multiple possible outputs for this actions ('error')
# and 'msg', it is possible to retrieve a subset. If only one output is
# asked, then its value is returned by the function. Else a dictionnary
# is returned.
# Then inputs are specified through unordered arguments. There must always
# be given as bytes, the requester is in charge to send it as hex to the web
# server. If some day the Web API changes, and some arguments are not expected
# to be in hexadecimal, changes will be needed.
error_message = req.do_action('send_cmd', 'error', ciphertext=b'\xff', nonce=b'\xff')
# do awesome things to find the flag
```
### Example of usage with server communication using 'option' parameters:
```python
from ch_requester import NCRequester
if __name__ == "__main__":
R = NCRequester(13397)
# adding actions to the requester
# first give the name of the action, and must match the option
# paramete of the server-side.
# then specify a tuple of inputs that are needed for this action
# then specify a tuple of outputs that can given in return.
# No particular ordering is needed here.
R.add_action("insert_key", ("key",), ("msg"))
R.add_action("unlock", (), ("msg",))
# we then open the connection (using pwntools)
R.open()
# some challenges print a line to welcome the challenger
# we can skip it
R.flush_line()
# As for the Web API, we can execute action, except this time
# the user is responsible to put input data into the correct
# format used by the server-side.
msg = req.do_action("insert_key", "msg", key=(b"\x00" * 16).hex())
print(msg)
flag = req.do_action("unlock", "msg")
# do awesome things to find the flag
R.close()
```
### Example of usage with server communication without 'option' parameters:
```python
from ch_requester import NCRequester
from base64 import b64decode
if __name__ == "__main__":
R = NCRequester(13370)
# some challenges don't use the 'option' parameters
# so you can send your own dictionnary payload to the server
# we then open the connection (using pwntools)
R.open()
# some challenges print a line to welcome the challenger
# we can skip it
R.flush_line()
PAYLOAD = {'msg': 'request'}
ciphertext = b64decode(req.send_recv_raw_payload(PAYLOAD, 'ciphertext'))
# do awesome things to find the flag
R.close()
```
