Hi Mani,

In the case of SFTP key based auth :

• Sever should have the public key, which will be linked to the user id in the known_host file under .ssh folder
• The client should have the private key

So in the case of PI irrespective of inbound/outbound it acts as a client, hence PI need to have the private key and SFTP server needs to have a public key.

There are 2 ways to generate SSH Keys :

• Use PuttyKeyGen tool to generate SSH key pair, and provide the public key to SFTP guys and using OpenSSL commands convert the PuttyGetGen Private key to NWA format private key.
• Create a Private/PublicKey pair in NWA , convert the Public key to SSH format public key and provide the same to a third party.

Use this wiki for reference.
