SFTP key based authentication
I have to establish SFTP connectivity with 3rd party using key authentication.
Based on my understanding,
1. SFTP communication is done over SSH so we need to exchange keys.
2. Here we do not need to generate the Public and Private key and get it certified by CA.
3. Private key which is being stored in NWA for SFTP communication - My understanding on this is that in case of inbound communication it is used to decrypt the data encrypted via corresponding Public key. While in case of outbound communication, it is used to client authentication.
Can you please let me know if above points are true from SFTP standpoint.
