Now that Ansible is installed, you must configure SSH key-based authentication (which uses asymmetric cryptography) from the control node to the managed nodes for Ansible to work seamlessly. You will need to generate a key pair on your control node and transfer the public key to the managed nodes. Use the command ssh-keygen to generate the key pair. The keys are stored in your home directory inside the .ssh folder. The default keys are named id_rsa.pub (public key) and id_rsa (private key). To enable SSH key-based authentication on the managed nodes, run the following command on your control node:

Note that if you are using Windows as an operating system, depending on the OS version, you'll need to install OpenSSH to have access to the ssh-keygen. In this tutorial you'll find all the ways you can generate a key pair on Windows.
Now, this is where the cryptography package comes into play. You'll need to import the serialization module from the package for loading an RSA key. For simplicity's sake, I generated a public/private key pair using the ssh-keygen without a password on the .ssh folder inside my working directory. Now all you have to do is load said keys: 2ff7e9595c
