# ssh-audit
[![build status](https://api.travis-ci.org/arthepsy/ssh-audit.svg)](https://travis-ci.org/arthepsy/ssh-audit)
**ssh-audit** is a tool for ssh server auditing.
## Features
- SSH1 and SSH2 protocol server support;
- grab banner, recognize device or software and operating system, detect compression;
- gather key-exchange, host-key, encryption and message authentication code algorithms;
- output algorithm information (available since, removed/disabled, unsafe/weak/legacy, etc);
- output algorithm recommendations (append or remove based on recognized software version);
- output security information (related issues, assigned CVE list, etc);
- analyze SSH version compatibility based on algorithm information;
- historical information from OpenSSH, Dropbear SSH and libssh;
- no dependencies, compatible with Python 2.6+, Python 3.x and PyPy;
## Usage
```
usage: ssh-audit.py [-bnv] [-l <level>] <host[:port]>
-1, --ssh1 force ssh version 1 only
-2, --ssh2 force ssh version 2 only
-b, --batch batch output
-n, --no-colors disable colors
-v, --verbose verbose output
-l, --level=<level> minimum output level (info|warn|fail)
```
* batch flag `-b` will output sections without header and without empty lines (implies verbose flag).
* verbose flag `-v` will prefix each line with section type and algorithm name.

## ChangeLog
### v1.6.0 (2016-10-14)
- implement algorithm recommendations section (based on recognized software)
- implement full libssh support (version history, algorithms, security, etc)
- fix SSH-1.99 banner recognition and version comparison functionality
- do not output empty algorithms (happens for misconfigured servers)
- make consistent output for Python 3.x versions
- add a lot more tests (conf, banner, software, SSH1/SSH2, output, etc)
- use Travis CI to test for multiple Python versions (2.6-3.5, pypy, pypy3)
### v1.5.0 (2016-09-20)
- create security section for related security information
- match and output assigned CVE list and security issues for Dropbear SSH
- implement full SSH1 support with fingerprint information
- automatically fallback to SSH1 on protocol mismatch
- add new options to force SSH1 or SSH2 (both allowed by default)
- parse banner information and convert it to specific sofware and OS version
- do not use padding in batch mode
- several fixes (Cisco sshd, rare hangs, error handling, etc)
