Note: SSH Keys from other programs may be converted to the required SGX 5150

SSH Server: Authorized Users
The SSH Server Authorized Users are used by all applications that play the role of an SSH Server
and specifically Tunneling in Accept Mode. Every user account must have a Password.
The user's Public Keys are optional and only necessary if public key authentication is wanted.
Using public key authentication will allow a connection to be made without the password being
asked at that time.
Note: When uploading the security keys, ensure the keys are not compromised in
transit.
