Generate a New SSH Host Identity Key

You can generate a new SSH Host Identity Key.

1. Select Deployment > SSH Host Identity Key.
2. Next to Create new SSH Host Identity Key, click Go!
3. Type a Host Name, using no spaces or special characters.
4. Select the Key Type as either ssh-rsa or ssh-ed25519.
   Note: When you switch to defaultSFTP=2.0 in the sftp.properties file, the system supports only the RSA key algorithm. The ssh-dss host key algorithm is not supported since it is legacy and weak.

   If you want to generate keys using ssh-dss key-type, then you must include the property sftp.defaultSFTP=1.0 in the customer_overrides.properties file.

   If you want to use ssh-dss algorithm, you can generate it using an external tool and check-in (For more information, see Check in an SSH Host Identity Key) the key into Sterling B2B Integrator and use it.

   Important: The key type ssh-ed25519 is only available for SFTP 2.0 from Sterling B2B Integrator v6.2.0.1 onwards.
5. For ssh-rsa, select the Key Length from the following options:
   • 768
   • 1024
   • 1536
   • 2048
   Note: The longer the key length, the more secure the key.
   For ssh-ed25519, select the Key Length as 256.
6. Type any Key Comments associated with this key. Comments are not required.
7. Click Next.
8. Confirm your entries and click Finish.
   Note: You do not need to check in keys generated from within Sterling B2B Integrator.
