Note: SSH Keys from other programs may be converted to the required SGX 5150
format. Use Open SSH to perform the conversion.
SSH Server: Authorized Users
The SSH Server Authorized Users are used by all applications that play the role of an SSH Server
during 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.
