# Hashcat Python Plugin Quickstart
|
||
|
||
## Introduction
|
||
|
||
Hashcat v7 introduces a `Python plugin bridge` that allows you to write and integrate custom hash-matching algorithms directly in Python. This plugin system fits into the regular cracking workflow by replacing or extending internal kernel routines.
|
||
|
||
When enabled, Hashcat uses the plugin’s `calc_hash()` function to compute hash candidates for verification, making it easy to experiment with new or obscure algorithms without modifying core C code or writing OpenCL/CUDA kernels.
|
||
|
||
This guide demonstrates how to quickly customize such an algorithm using pure Python. Whether you're prototyping a new hash mode, supporting a proprietary format, or simply prefer high-level development, Python plugins make the process fast and straightforward.
|
||
|
||
No C required. No recompilation. Just write your logic in Python using `calc_hash()`, and you're ready to crack.
|
||
|
||
You can use any Python modules you like.
|
||
|
||
## Quick Start
|
||
|
||
A benchmark is a good way to verify that your setup is working correctly.
|
||
|
||
Hashcat mode `73000` is preconfigured to load a generic Python plugin from the source file `Python/generic_hash_mp.py`:
|
||
|
||
```
|
||
hashcat -m 73000 -b
|
||
```
|
||
|
||
If you encounter issues with your Python installation, refer to `hashcat-python-plugin-requirements.md`.
|
||
|
||
To learn how to modify the plugin source, see `hashcat-python-plugin-development-guide.md`.
|
||
|
||
## Yescrypt in One Line
|
||
|
||
### Generate a Yescrypt Test Hash
|
||
|
||
```
|
||
echo password | mkpasswd -s -m yescrypt
|
||
```
|
||
|
||
Example output:
|
||
|
||
```
|
||
$y$j9T$uxVFACnNnGBakt9MLrpFf0$SmbSZAge5oa1BfHPBxYGq3mITgHeO/iG2Mdfgo93UN0
|
||
```
|
||
|
||
### Prepare the Hash Line for Hashcat
|
||
|
||
```
|
||
$y$j9T$uxVFACnNnGBakt9MLrpFf0$SmbSZAge5oa1BfHPBxYGq3mITgHeO/iG2Mdfgo93UN0*$y$j9T$uxVFACnNnGBakt9MLrpFf0$
|
||
```
|
||
|
||
(Use the full hash before the `*` and the salt portion after the `*`.)
|
||
|
||
Hashcat modes `73000` and `72000` are generic modes that do not parse the hash, which can lead to redundancy.
|
||
|
||
Refer to `hashcat-python-plugin-development-guide.md` to learn how to develop plugins for the generic hash mode.
|
||
|
||
### Plugin Code
|
||
|
||
Install the required module:
|
||
|
||
```
|
||
pip install pyescrypt
|
||
```
|
||
|
||
Then in your plugin (either `generic_hash_mp.py` for `-m 73000` or `generic_hash_sp.py` for `-m 72000`):
|
||
|
||
**Note for Windows and MacOS users:** Mode `73000` automatically switches to `generic_hash_sp.py`, so be sure to edit that file.
|
||
|
||
```python
|
||
from pyescrypt import Yescrypt, Mode
|
||
|
||
# Self-test pair
|
||
ST_HASH = "$y$j9T$uxVFACnNnGBakt9MLrpFf0$SmbSZAge5oa1BfHPBxYGq3mITgHeO/iG2Mdfgo93UN0*$y$j9T$uxVFACnNnGBakt9MLrpFf0$"
|
||
ST_PASS = "password"
|
||
|
||
def calc_hash(password: bytes, salt: dict) -> str:
|
||
return Yescrypt(n=4096, r=32, p=1, mode=Mode.MCF).digest(
|
||
password=password,
|
||
settings=hcshared.get_salt_buf(salt)
|
||
).decode("utf-8")
|
||
```
|
||
|
||
That’s it.
|
||
|
||
### Run Regularly
|
||
|
||
```
|
||
hashcat -m 73000 yescrypt.hash wordlist.txt
|
||
```
