To access your instances using SSH, generate an SSH key pair, associate the public key with your instances, and use the private key to log in to the instances using SSH.
Apr 19, 2019 ssh-keygen 2. In order to generate a unique set of key pairs and store them, you will be prompted to provide a directory where the key pair will be stored, or you may press enter to choose the. The ssh-keygen command creates two files, key@ssh, and [email protected], which contain private and public key, respectively. It is recommended to hide the private key for security purposes, copy the public key to the remote host. After copying this key to a remote host, we can establish a connection using the SSH key, not by the password.
Ssh-keygen Command Line Options. Ssh-keygen is used to generate keys and it provides a number of options to ease the key pair management, tighten the security and increase the flexibility. The following options are some of the prominent options which may come handy when managing a server. Generating Your SSH Public Key Many Git servers authenticate using SSH public keys. In order to provide a public key, each user in your system must generate one if they don’t already have one. This process is similar across all operating systems.
Note:
You can’t use SSH keys to log in to a Windows instance. To log in to your Windows instance using RDP, see Accessing a Windows Instance Using RDP.
Caution:
Keep your SSH keys secure. Lay down policies to ensure that the keys aren’t lost or compromised when employees leave the organization or move to other departments. If you lose your private key, then you can’t access your instances. For business continuity, ensure that the SSH keys of at least two IT system administrators are added to your instances.

Generating an SSH Key Pair on UNIX and UNIX-Like Systems
Use the following procedure to generate an SSH key pair on UNIX and UNIX-like systems:
Run the ssh-keygen
command.
You can use the -t
option to specify the type of key to create.
For example, to create an RSA key, run:
You can use the -t
option to specify the length (bit size) of the key, as shown in the following example:
The command prompts you to enter the path to the file in which you want to save the key.
A default path and file name are suggested in parentheses. For example: /home/
user_name
/.ssh/id_rsa
. To accept the default path and file name, press Enter. Otherwise, enter the required path and file name, and then press Enter.
The command prompts you to enter a passphrase.
The passphrase is not mandatory if you want to log in to an instance created using an Oracle-provided image. However, it is recommended that you specify a passphrase to protect your private key against unauthorized use.
Note:
With some images provided on Oracle Marketplace, the use of a passphrase might be mandatory.
The command generates an SSH key pair consisting of a public key and a private key, and saves them in the specified path. The file name of the public key is created automatically by appending .pub
to the name of the private key file. For example, if the file name of the SSH private key is id_rsa
, the file name of the public key would be id_rsa.pub
.
Make a note of the path and file names of the private and public keys. When you create an instance, you must specify the SSH public key value. When you log in to an instance, you must provide the path to the corresponding SSH private key and you must enter the passphrase when prompted.
Generating an SSH Key Pair on Windows
You can generate an SSH key pair on a Microsoft Windows machine by using an application such as PuTTY. See the tutorial, Creating SSH Keys for Use with Oracle Cloud Services.
