Creating a Key pair

To generate a new Key pair, run the following commands on your home computer.

1. Open your terminal and run the following command under your username.

   [local]$ ssh-keygen -t rsa

   This creates a public/private keypair of the type (-t) rsa.

   Generating a public/private rsa key pair.
   Enter the file in which you wish to save they key (i.e., /home/username/.ssh/id_rsa):
   

2. The prompt defaults to save the new key pair in the /home/username/.ssh/ directory and name it 'id_rsa'. Unless you want to change the location or name of the file, just click Enter on your keyboard to continue.

   Enter a passphrase (leave empty for no passphrase).

3. It's recommended that you do not use a passphrase. Click Enter on your keyboard to continue.

   Enter same passphrase again:

4. Click Enter on your keyboard to continue.
5. When finished, click Enter on your keyboard.

   The following message appears:

   Your identification has been saved in /home/username/.ssh/id_rsa
   Your public key has been saved in /home/username/.ssh/id_rsa.pub
   
   The key fingerprint is:
   ar:bc:d3:9e:g3:1f:63:6f:6b:32:2e:97:ee:42:e1:be username@server.dreamhost.com
   
   The key’s randomart image is:
   
   +--[ RSA 2048]----+
   | ..+**B.o++o     |
   |  . o+==o. o     |
   |    . .oo.=      |
   |      . +E+ .    |
   |        S .      |
   |                 |
   |                 |
   |                 |

6. You can view the new private and public key by running the following:

   [local]$ ls -1 ~/.ssh/
   id_rsa
   id_rsa.pub

7. Finally, import the public key into your DreamCompute dashboard.
