# ssh-audit
**ssh-audit** is a tool for ssh server auditing.
## Features
- grab banner, detect ssh1 protocol and zlib compression;
- gather key-exchange, host-key, encryption and message authentication code algorithms;
- output algorithm information (available since, removed/disabled, unsafe/weak/legacy, etc);
- analyze SSH version compatibility based on algorithm information;
- historical information from OpenSSH and Dropbear SSH;
- no dependencies, compatible with python2 and python3;
## Usage
```
usage: ssh-audit.py [-nv] host[:port]
-v verbose
-n disable colors
```
Verbose flag will fill each row, i.e, not leave blanks, for easier usage with _batch_ scripts or with manual grepping.
