# pyJARM
[](https://pypi.python.org/pypi/pyjarm)
[](https://github.com/PaloAltoNetworks/pyjarm/blob/main/LICENSE)
[](https://github.com/psf/black)
## Overview
pyJARM is a convenience library for the JARM fingerprinting tool. This library is based on the original python implementation [here](https://github.com/salesforce/jarm).
It requires python 3.7+.
## Installation
```
pip install pyjarm
```
## Usage
### Command Line
```
usage: jarm [-h] [-i INPUT] [-d] [-o OUTPUT] [-4] [-6] [-c [CONCURRENCY]]
[--proxy PROXY] [--proxy-auth PROXY_AUTH] [--proxy-insecure]
[--timeout TIMEOUT] [--suppress]
[scan]
Enter an IP address/domain and port to scan or supply an input file.
positional arguments:
scan Enter an IP or domain to scan.
optional arguments:
-h, --help show this help message and exit
-i INPUT, --input INPUT
Provide a list of IP addresses or domains to scan, one
domain or IP address per line. Ports can be specified
with a colon (ex. 8.8.8.8:8443)
-d, --debug [OPTIONAL] Debug mode: Displays additional debug
details
-o OUTPUT, --output OUTPUT
[OPTIONAL] Provide a filename to output/append results
to a CSV file.
-4, --ipv4only [OPTIONAL] Use only IPv4 connections (incompatible
with --ipv6only).
-6, --ipv6only [OPTIONAL] Use only IPv6 connections (incompatible
with --ipv4only).
-c [CONCURRENCY], --concurrency [CONCURRENCY]
[OPTIONAL] Number of concurrent connections (default
is 2).
--proxy PROXY [OPTIONAL] Use proxy (format
http[s]://user:pass@proxy:port). HTTPS_PROXY env
variable is used by default if this is not set. Set
this to 'ignore' to ignore HTTPS_PROXY and use no
proxy.
--proxy-auth PROXY_AUTH
[OPTIONAL] Send this header in Proxy-Authorization
(when using proxy).
--proxy-insecure [OPTIONAL] Do not verify SSL_CERTIFICATES (only when
HTTPS proxy is set).
--timeout TIMEOUT [OPTIONAL] Timeout to wait for connection attempts.
Default is 20 seconds
--suppress [OPTIONAL] Suppresses any exception or warning logging.
```
**Example**
```
$ pyjarm google.com
Target: google.com:443
JARM: 27d40d40d29d40d1dc42d43d00041d4689ee210389f4f6b4b5b1b93f92252d
```
### Scripted without asyncio
```
from jarm.scanner.scanner import Scanner
print(Scanner.scan("google.com", 443))
('27d40d40d29d40d1dc42d43d00041d4689ee210389f4f6b4b5b1b93f92252d', 'google.com', 443)
```
### Scripted with asyncio
```
import asyncio
from jarm.scanner.scanner import Scanner
print(asyncio.run(Scanner.scan_async("google.com", 443)))
('27d40d40d29d40d1dc42d43d00041d4689ee210389f4f6b4b5b1b93f92252d', 'google.com', 443)
```
