## Install
All you need to do is
```sh
pip install ctfbox
```

## Usage

### Common
```python
from ctfbox import * # Will not import the pwn part, please check the PWN Usage section below
# enjoy it
```
### PWN
[PWN Usage](#pwn-1)
## Functions
Please refer to docstring for function's signatures and usages
### utils
Some useful functions, close to intuition
- url: `url_encode()`, `url_decode()`, `force_url_encode()`
- html: `html_encode()`, `html_decode()`
- base16: `base16_encode()`, `base16_decode()`
- base32: `base32_encode()`, `base32_decode()`

- random: `random_int()`, `random_string()`
- prase od command data: `od_parse()`
- A decorator to make it multi-threaded: `Threader()`
- Decrypted in the usual way: `auto_decode()`
  

### WEB
- generate flask pin: `get_flask_pin()`
- generate flask session: `flask_session_encode()`, `flask_session_decode()`
(***⚠️ There is no flask dependency in ctfbox itself, the following two functions need to install the dependency by yourself***)
- build a simple file server: `provide()`
- burte force hash for ctf verification code: `hashAuth()`
- Send raw request by python-requests: `httpraw()`
- generate gopher reuqests: `gopherraw()`
- generate php serialize escape payload: `php_serialize_escape`, `php_serialize_escape_s2l()`, `php_serialize_escape_l2s()`
- change normal stirng to php serialize S string: `php_serialize_S()`
- php serialize
   - `serialize()`
   - `unserialize()`
   - `serialize_to_file()`
   - `unserialize_from_file()`
   - ...

   for more information, please check docstring and [here](https://github.com/mitsuhiko/phpserialize)
- generate php soapClient class payload for ssrf: `soapclient_ssrf()`
- network scan
  - scan network path: `scan()`
  - scan for network backup file: `bak_scan()`
- generate reverse shell command: `reshell()`
- use for out of band: `OOB()`
- build a server for blindXXE: `blindXXE()`
- generate gopher payload for attack redis
  - write webshell: `gopherredis_webshell()`
  - write crontab: `gopherredis_crontab()`
  - ssh authorized keys: `gopherredis_ssh()`
  - rce by master-slave replication: `gopherredis_msr()`
- generate gopher payload for attack fastcgi
  - arbitrary code execution: `gopherfastcgi_code()`
- source code leaks, support .git .svn .DS_Store: `leakdump()`
- reverse mt_rand seed without brute force: `reverse_mt_rand()`

### REVERSE
- print data in hex format: `printHex()`
- pack number into bytes: `p16()`, `p32()`, `p64()`
- unpack number from bytes: `u16()`, `u32()`, `u64()`

### MISC
- provide common file signatures and function to patch a file
  - patch file signature: `repair_fileheader()`
- fix zip fake encrypt: `repair_zip_fake_encrypt()`


### CRYPTO
- srand for multiple platforms: `windows_srand()`, `linux_srand()`, `android_srand()`, 
- get random integer from multiple platforms: `windows_rand()`,  `linux_rand()`, `android_nextInt()`, `android_nextInt_bound()`

### PWN
- Usage
   ```python
   # Doesn't support Windows
   from pwn import * # import pwntools
   # set pwntools config...
   # context.os = 'linux'
   # context.log_level = 'debug'
   # context.arch = 'amd64'
   from ctfbox.pwntools.config import Config # import confit for pwn part of ctfbox
   # set necessary config 
   """
   Attributes:
   - local(bool) : connect to local binary / remote address, default: True
   - bin(str)    : the binary path, e.g. './pwn'
   - address(str): the remote address, e.g. '127.0.0.1:2333'
   - pie(bool)   : whether the memory address is randomized, default: False
   """
   Config.local = True
   Config.address = "127.0.0.1:2333"
   Config.bin = "./bin"
   # import pwn part
   from ctfbox.pwn import *
   ```
   now you can use the attributes/functions below
   ```
   slog // empty dictionary, you can set the leaked address and corresponding name. e.g. slog['libc'] = libc_addr
   elf  // pwntools.ELF(binaray)
   cn   // a connect to local binary or remote address
   re   // lambda of cn.recv(m, t)
   recv // lambda of cn.recv()
   ru   // lambda of cn.recvuntil(x)
   rl   // lambda of cn.recvline()
   sd   // lambda of cn.send(x)
   sl   // lambda of cn.sendline(x)
   ia   // lambda of cn.interactive()
   sla  // lambda of cn.sendlineafter(a, b)
   sa   // lambda of cn.sendafter(a, b)
   ft   // ft(arg, f=pwnlib.util.cyclic.de_bruijn(), l=None) lambda of flat(*arg, filler=f, length=l)
   gdba // gdba(bps) debug, argument bps save the breakpoint address, breakpoint can also be automatically set when pie is turned on, need pmap command
   slog_show // print all set slogs, in hexadecimal format
   ```
