How to Use SFTP for File Transfers (Uploads & Downloads)

This guide explains how to securely use SFTP to upload and download files, ensuring reliable data exchange between your local device and the server.

SFTP (Secure File Transfer Protocol) is an Internet protocol developed as an extension of SSH (Secure Shell) by the Internet Engineering Task Force (IETF). It facilitates secure access, file transfers, and file management over a network. Operating on port 22, SFTP employs encryption and authentication for secure transfers, making it suitable for file exchanges over VPNs or secured environments. Benefits of SFTP include robust encryption, support for public key authentication, large file handling, and seamless integration with firewalls and VPN systems.
