ansible-role-ssh-ca

Ansible role to deploy a basic SSH certificate authority.

It is implemented as a simple wrapper above ssh-keygen, which is deployed on a server. It supports issuing host certificates as well as user certificates.

Limitations

I currently only use this in my home lab, and it should not be used in more critical environments. Notable, it has the following limitations:

• No expiration date and no mechanism to issue new certificates
• No mechanism to revoke certificates
• No mechanism to roll over CA key pair

Usage

The following variables must be set before calling the role:

• ssh_ca_dir: Working directory for the certificate authority
• ssh_ca_user_ca_private_key: Private key of the SSH user CA
• ssh_ca_user_ca_public_key: Public key of the SSH user CA
• ssh_ca_host_ca_private_key: Private key of the SSH host CA
• ssh_ca_host_ca_public_key: Public key of the SSH host CA
