To work with the Oracle Cloud Infrastructure once the Oracle Data Transforms Compute Node is built, you have to provide a SSH Public Key to allow you to login to the node.

In order to build your SSH keys, perform the following steps:

1. In a terminal window, generate the SSH key using the following command:

   $ ssh-keygen Generating public/private rsa key pair.

2. Enter the path to store this file. By default, this gets saved in your home directory under a hidden folder called .ssh. Change this default location, if required.

   Enter file in which to save the key (/Users/johndoe/.ssh/id_rsa): <Return>

3. Enter a passphrase using your key.

   Enter passphrase (empty for no passphrase): <passphrase>

4. Re-enter the passphrase to confirm it.

   Enter same passphrase again: <passphrase>

5. Check the results.

   The key fingerprint (a colon separated series of two-digit hexadecimal values) is displayed. Check if the path to the key is correct. In the above example, the path is /Users/johndoe/.ssh/id_rsa.pub. You have now created a public and private key pair.
