Download and Upload Files with SFTP Securely

SFTP (SSH File Transfer Protocol) is secured protocol to transfer files between local and remote server. To required SSH server running on the remote system. This protocol encrypts the transfer of data between local and remote system. As SFTP provides secure data transfer, so we recommend it over FTP protocol.
