4. Generate SSH keys: If you haven’t generated an SSH key pair yet, open the PowerShell as an administrator and run the command:
“`
ssh-keygen -t rsa
“`
This will create an RSA key pair in the default location: `C:UsersYourUsername.ssh` (Replace “YourUsername” with your actual username).
5. Edit sshd_config: Locate the OpenSSH config file called “sshd_config” in `C:ProgramDatassh`. Open the file with a text editor and make the following changes:
– Uncomment the line that says `#PubkeyAuthentication yes` by removing the “#” symbol.
– Uncomment the `#AuthorizedKeysFile .ssh/authorized_keys` line.
– If you wish to change the default listening port, find and uncomment the `#Port 22` line and replace “22” with your desired port number.
6. Add your public key to authorized_keys: Copy your public SSH key (the one ending in “.pub”) from your client machine and add it to the `authorized_keys` file on the Windows server. If the file doesn’t exist, create it in the `C:UsersYourUsername.ssh` directory. Make sure each key is on a new line.
7. Restart the OpenSSH server service: Go back to the Services app in Windows, find “OpenSSH SSH Server,” right-click, and select “Restart” to apply the changes.
Now you should be able to connect to your Windows SSH server remotely using an SSH client like PuTTY or the built-in SSH command on UNIX-based systems.

scp [options] [source] [destination]
“`
For example, to transfer a file named “example.txt” from a local machine to a remote server, you’d enter:
“`
scp example.txt username@remote_server_ip:/path/to/destination
“`
Similarly, to transfer a file from a remote server to your local machine, just swap the source and destination:
“`
scp username@remote_server_ip:/path/to/source/example.txt /path/to/local/destination
“`
– WinSCP: Download and install the WinSCP application from its official website. After launching WinSCP, enter your SSH credentials and connect to the remote server. From there, you can simply drag and drop files between your local machine and the remote server to transfer them securely.
2. SFTP
SFTP is another secure file transfer method that’s built into OpenSSH. You can also use third-party applications like FileZilla or WinSCP for this.
– OpenSSH: Open the command prompt and type the following command to initiate an SFTP session:
“`
sftp username@remote_server_ip
“`
Once connected, you can use various SFTP commands like `get`, `put`, and `ls` to navigate and transfer files securely between your local machine and the remote server.
– FileZilla or WinSCP: Download and install either FileZilla or WinSCP (if you haven’t already). Enter your SSH credentials and connect to the remote server. You can then easily drag and drop files between your local machine and the remote server for secure file transfers.
In summary, transferring files securely via SCP or SFTP on Windows is straightforward when you’re working with Secure Shell. Utilize either OpenSSH’s built-in tools or third-party applications like WinSCP or FileZilla to ensure your data transfers are secure and protected.
