Generating the Secure Shell (SSH) Key

Legacy orchestrator only supports public and private keys in PEM format. However, when generating the SSH key on Ubuntu 20.04, it is not in PEM format.

To generate the SSH Key

1. Access SSH to the Legacy orchestrator via port 22.

2. Enter one of two below commands to generate the key:

   • RSA key:

     • PEM format: ssh-keygen -t rsa -m pem -b 2048

     • OpenSSH format: ssh-keygen -t rsa -b 2048
   • ECDSA key: ssh-keygen -t ecdsa -m pem

3. If prompted to Enter file in which to save the key (/home/visionems/.ssh/id_rsa): enter

4. If prompted to Enter passphrase (empty for no passphrase); input the password for the key file or enter to empty pass.

5. If prompted to Enter the same passphrase again; input the password for the key file or enter to empty pass.

After step 5, give the key two files under the location you entered in the third step.
