SFTP Server for Windows: A Comprehensive Guide for Dev

Hello Dev! Are you looking for a secure way to transfer files between your Windows machines? SFTP might be the solution you need. In this article, we’ll walk you through everything you need to know about SFTP server for Windows. From installation to configuration, we’ve got you covered.

What is SFTP?

Before we dive into the specifics of SFTP server for Windows, let’s first define what SFTP is. SFTP stands for Secure File Transfer Protocol. As the name suggests, it’s a secure way to transfer files between machines. It uses encryption to secure the data in transit, making it a popular choice among businesses and individuals who value their privacy.

How is SFTP different from FTP?

SFTP is often compared to FTP, but they are different protocols. While FTP is an unencrypted protocol, SFTP uses SSH to encrypt the data in transit. This makes SFTP a more secure option for file transfers. Additionally, SFTP uses a different port number than FTP (port 22 instead of port 21).

Why use SFTP on Windows?

If you’re using Windows machines and need to transfer files securely, SFTP is a great option. It’s easy to set up and use, and it’s compatible with a variety of file transfer clients. Whether you’re transferring sensitive data or just want to ensure your files are secure, SFTP is a reliable choice.

Installing an SFTP Server on Windows

The first step in using SFTP on Windows is to install an SFTP server. There are several options available, but we recommend using OpenSSH. Here’s how to install OpenSSH on Windows:

Step 1: Enable the OpenSSH Client and Server

To install OpenSSH on Windows, you’ll need to enable the OpenSSH client and server features. Here’s how:

Step
Command
1
Open PowerShell as an administrator.
2
Type the following command: Get-WindowsCapability -Online | ? Name -like 'OpenSSH*' | Add-WindowsCapability -Online

This will install the OpenSSH client and server on your Windows machine.

Step 2: Configure the OpenSSH Server

Once you’ve installed the OpenSSH server, you’ll need to configure it. Here’s how:

Step
Command
