## Description
`bftool` is a python module and script, with a custom worker pool for the distribution of function execution into processes and threads based on a initial input, so you only need to focus on the functionality and not in the distribution of its execution.
## Concepts
### Time consuming functions
In the context of `bftool` the weight of a function is based on the time spent from when it was called to its finish.
Based on that we can conclude that this operations are most of the time heavy, since usually require more time to finish:
- File I/O.
- Networking I/O.
- N Cycles (FOR, WHILE, ...).
- Force waits (like `sleep`).
And this operations are usually light
- Math.
- Variable assign to a known value.
- Some hash calculations.
## Quick example
### As a module
`bftool` auto detects if the function requires or not parallelism and based on that spawn the workers.
```python
import hashlib
import string
import bftool
secret = "zz"
target = hashlib.sha3_512(secret.encode()).hexdigest()
def calc_hashes(salt: str, raw_password: str) -> tuple[str, str, str, str]:
salt_password = (salt + raw_password).encode()
return salt, raw_password, hashlib.blake2b(salt_password).hexdigest(), hashlib.sha3_512(
salt_password).hexdigest()
def cracked(hashes: tuple[str, str, str, str]) -> bool:
return target in hashes[2:]
def success(result: tuple[str, str, str, str]):
print(f"[+] \"{result}\n", end="")
def main():
arguments = bftool.Arguments(
calc_hashes,
bruteforce_rules={
"raw_password": {
"minlength": 1,
"maxlength": 1,
"elements": string.ascii_letters,
"string-join": True
},
"salt": {
"minlength": 1,
"maxlength": 1,
"elements": string.ascii_letters,
"string-join": True
}
}
)
pool = bftool.Pool(
calc_hashes,
arguments,
cracked,
success,
max_processes=3,
max_threads=3
)
print("Fuzzing time:", pool.run())
if __name__ == "__main__":
main()
```
### As a script
```shell script
python -m bftool --help
```
```
usage: bftool [-h] [-mt MAX_THREADS] [-mp MAX_PROCESSES] [-w WORDLIST] [-b BRUTEFORCE] [-sf SUCCESS_FUNCTION] [-cf CHECK_FUNCTION] [-sp SCRIPT_PATH] expression
positional arguments:
expression expression that will result in a callable
optional arguments:
-h, --help show this help message and exit
-mt MAX_THREADS, --max-threads MAX_THREADS
Maximum number of threads per process
-mp MAX_PROCESSES, --max-processes MAX_PROCESSES
Maximum number of process to have active at the same time
-w WORDLIST, --wordlist WORDLIST
File wordlist to use based on "{'argument_1': FILE_PATH, ...}"
-b BRUTEFORCE, --bruteforce BRUTEFORCE
Generate a virtual wordlist based on rules "{'argument_1': {'elements': [element_1, ...], 'minlength': INT, 'maxlength': INT, 'string-join': BOOL}, ...}"
-sf SUCCESS_FUNCTION, --success-function SUCCESS_FUNCTION
Function to pass the success result to (default is custom 'print')
-cf CHECK_FUNCTION, --check-function CHECK_FUNCTION
Function useful to check the output (default is 'lambda output: output')
-sp SCRIPT_PATH, --script_path SCRIPT_PATH
Python script to import
```
