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.
