  2. To export the private key, select Export OpenSSH key from the Conversions menu; to export the public key, click Save public key from the main window; Public keys typically use the.pub suffix. By convention, the private key is usually called idrsa and the public key idrsa.pub, but this isn’t a requirement. It’s common to have many keys with more descriptive filenames, for instance.

Jul 29, 2019  The secure private key ensures that you are the only person who can encrypt the data that is decrypted by the public key. Step 2- Copy Public Key to the Ubuntu Server First, get the IP address of the Ubuntu server you want to connect to.

SSH keys are a way to identify trusted computers, without involving passwords. The steps below will walk you through generating an SSH key and adding the public key to the server.

Step 1: Check for SSH Keys

First, check for existing SSH keys on your computer. Open Git Bash, Cygwin, or Terminal, etc. and enter: free meme making apps on mac

Check the directory listing to see if you already have a public SSH key. By default, the filenames of the public keys are one of the following:

  • id_dsa.pub
  • is_ecdsa.pub
  • id_ed25519.pub
  • id_rsa.pub

If you see an existing public and private key pair listed (for example id_rsa.pub and id_rsa) that you’d like to use, you can skip Step 2 and go straight to Step 3.

Step 2: Generate a new SSH key

With your command line tool still open, enter the text shown below. Make sure you substitute in your email address:

You’ll be asked to enter a passphrase, or simply press Enter to not enter a passphrase:

After you enter a passphrase (or just press Enter twice), review the fingerprint, or ‘id’ of your SSH key:

Step 3: Add your key to the ssh-agent

To configure the ssh-agent program to use your SSH key, first ensure ssh-agent is enabled.

If you are using Git Bash, turn on the ssh-agent with command shown below instead: Gsm key generation and encryption.

Then, add your SSH key to the ssh-agent:

Step 4: Add your SSH key to the server

To add your public SSH key to the server, you’ll copy the public SSH key you just created to the server. Substitute “username” with your username on the server, and “server.address.com” with the domain address or IP address of your server:

The server will then prompt you for your password:

That’s it! You should now be set up to connect to the server without having to authenticate.
