A quick post of how to work with ssh keys using MS azure.

Making a key pair:

ssh-keygen -t rsa

In this example, use the defaults. (Hit ENTER till the key is created.)

You should have a key in:

ls .ssh/id_rsa

Given an Azure Keyvault that you haver previously created, find that vault:

az keyvault list

For this example, let's call it "mykeyvault".

Upload the key.

az keyvault secret set --name sshkey --vault-name mykeyvault --file ~/.ssh/id_rsa

List the keys:

az keyvault secret list --vault-name mykeyvault

Now we can get the key:

az keyvault secret download --name sshkey --vault-name mykeyvault --file sshkey.pem

This should create a file which is the same as ~/.ssh/id_rsa. Prove it with diff.

diff ~/.ssh/id_rsa sshkey.pem
