## SSH Client certificate verification demo

Sole purpose of this repository is to demonstrate minimum setup for verification

of client ssh certificate when authenticating against ssh daemon (SSHD).

3 docker images will be built

 - Common volume with all keys (CA private/public key), and client key

 - SSH server image

 - SSH client image

Once containers are started, client will do the following

 - sign it's key using CA private key with validity period of 60 seconds

 - login to ssh server and write server hostname (container id) and time on

   standard output as long

 - repeat step above every 5 seconds as long as certificate is valid.

 - client container will stop once

All images are based on `debian:jessie` image

## Requirements

- Docker compose supporting compose file version >=3

- Docker daemon

## Usage

```

$ git clone https://github.com/toshke/sshd-certificate-authorization-demo

$ cd sshd-certificate-authorization-demo

$ docker-compose up

```

## Contributing

Couple of ideas for improving this demo

 - demonstrate host key validation on client side

 - demonstrate using authorized_keys file

Pull requests are welcome :)

## History

- (2017-09-12) Initial version demonstrating SSHD server verifying wether client

  key is signed with Certificate Authority (CA)
