To perform the following actions for Windows or Linux, you must have OpenSSL installed on your system.

  1. Sep 26, 2019  Manually generating your SSH key in macOS ›. To generate SSH keys in macOS, follow these steps: Enter the following command in the Terminal window. Ssh-keygen -t rsa. This starts the key generation process. When you execute this command, the ssh-keygen utility prompts you to indicate where to store the key.
  2. If you just want to share the private key, the OpenSSL key generated by your example command is stored in private.pem, and it should already be in PEM format compatible with (recent) OpenSSH. To extract an OpenSSH compatible public key from it, you can just run: ssh-keygen -f private.pem -y private.pub.

Supported SSH key formats. Azure currently supports SSH protocol 2 (SSH-2) RSA public-private key pairs with a minimum length of 2048 bits. Other key formats such as ED25519 and ECDSA are not supported. Create an SSH key pair. Use the ssh-keygen command to generate SSH public and private key files. By default, these files are created in the.

Generating the Private Key -- Windows

In Windows:

1. Open the Command Prompt (Start > Programs > Accessories > Command Prompt).

2. Navigate to the following folder:

Key

C:Program FilesListManagertclwebbincerts

3. Type the following:

openssl genrsa -out rsa.private 1024

4. Press ENTER. The private key is generated and saved in a file named 'rsa.private' located in the same folder.

NOTE The number '1024' in the above command indicates the size of the private key. You can choose one of five sizes: 512, 758, 1024, 1536 or 2048 (these numbers represent bits). The larger sizes offer greater security, but this is offset by a penalty in CPU performance. We recommend the best practice size of 1024.

Generating the Public Key -- Windows

1. At the command prompt, type the following:

2. Press ENTER. The public key is saved in a file named rsa.public located in the same folder.

Generating the Private Key -- Linux

1. Open the Terminal.

2. Navigate to the folder with the ListManager directory.

Create New Ssh Key

You can generate a secure shell (SSH) key pair for an Oracle Java Cloud Service instance on a UNIX or UNIX-like platform by using the ssh-keygen utility.
  1. From your computer, run the ssh-keygen utility.

    Specify a filename for the private key. Also specify the RSA type and a size of 2048.

    The command format is: ssh-keygen -b 2048 -t rsa -f filename

    For example: ssh-keygen -b 2048 -t rsa -f mykey

  2. When prompted, enter a passphrase for the private key, or press Enter to create a private key without a passphrase.

    Enter passphrase (empty for no passphrase): YourPassphrase

    Note:

    While a passphrase is not required, Oracle recommends using one as a security measure to protect the private key from unauthorized use. When you specify a passphrase, a user must enter the passphrase every time the private key is used.

  3. If you provided a passphrase, enter it a second time when prompted.

The ssh-keygen utility creates two files:

  • filename - The private key

  • filename.pub - The public key
