Many times when we login to a system, we use a username/password combination.
For example, to login to the DTCC portal, you enter a username/password combination into a web
form like what is displayed below
Another option for authentication, and one that is used by cloud computing infrastructure
environments such as AWS is to use a cryptographic key and pass the key to the server during
login.
In this lab, youll generate a cryptographic key to enable passwordless login to your Ubuntu VM.
Step 1:
Generate the keypair. On either your Windows10 VM or your Ubuntu VM, run the command: ssh-
keygen You should see output similar to the following:
Two files were created as a result of running this command:
The file id_rsa is readable ONLY by the owner because it is the RSA Private key. This file should
be guarded and treated as a password.
The other file, id_rsa.pub is the RSA public key associated with the private key file.
Step 2:
To enable login to your Ubuntu VM using the certificate (and without entering a password) copy
the id_rsa.pub file into your home directory in a file named .ssh/authorized_keys.
Step 3:
Login to your Ubuntu VM from your Windows 10 VM using the ssh command in a command
window. You will need to supply the -i option and include the name and location of your RSA
private key that you generated in step 1
