FTP, or "File Transfer Protocol" is a popular method of transferring files between two remote systems.
SFTP, which stands for SSH File Transfer Protocol, or Secure File Transfer Protocol, is a separate protocol packaged with SSH that works in a similar way over a secure connection. The advantage is the ability to leverage a secure connection to transfer files and traverse the filesystem on both the local and remote system.

When the setting up is completed all the instructions will be provided by as2gateway with the private key.
