How to use your vagrant box SSH credentials

By default, many Vagrant boxes install a SSH key for the default user of a virtual machine image. This is fully transparent and you can log in to the machine with the vagrant ssh command. But what if you want to log in with the standard ssh command, connect with rsync or run an Ansible playbook? This article shows how to find and reuse the connection parameters for your Vagrant box.

How Secure Are Ansible Vaults?

Encrypting credentials like SSH keys or database passwords and putting the encrypted file in a semi-public Git repository is both convenient and scary. Convenient because every user of the repository only has to know only one password. Scary because you now rely on encryption and passwords instead of other security practices. So the question arose in my team “Assuming there are no implementation errors, how secure are Ansible Vaults?” Since the first 10 Google results did not answer this question quick enough, I decided to read the source code and answer the question myself.
