Connect to server using SFTP and a public SSH key using FileZilla on Windows

SFTP (Secure File Transfer Protocol) is a secure way of transferring files between computers using SSH (Secure Shell). It is widely used to transfer files securely, as it provides a high level of encryption and authentication to protect the data during transfer. As an IT administrator, you may need to use SFTP to connect to a server and transfer files, and this can be done using FileZilla on Windows.

To get started, you will need to generate a private/public key pair. This can be done using the PuTTYgen utility. Open PuTTYgen and generate a key pair. Make sure to save the public and private keys, as they will be needed later.

Next, you will need to add the public key to the authorized_keys file on the server. This file is usually located in the .ssh folder in the user’s home directory. Depending on the server configuration, you may need to manually create the .ssh folder and authorized_keys file. Once the file is created, copy and paste the public key into it. Make sure to save and close the file.

Now that the public key is added to the server, you can configure FileZilla to connect to the server using SFTP. Open FileZilla and go to the Site Manager. Select “SFTP” as the protocol and enter the server’s address. In the “Login Type” dropdown, select “Interactive” and enter the username. Now, go to the “Advanced” tab, select “Authentication”, and then “Add Key File”. Browse to the private key file and select it.

Finally, you can connect to the server. Click “Connect” and enter the passphrase for the private key when prompted. If all goes well, you should be connected to the server and be able to transfer files securely.

As an IT administrator, you may be required to connect to a server securely using SFTP. By following the steps outlined above, you can easily configure FileZilla to connect to a server using SFTP and a public SSH key. This is a great way to ensure that your data is securely transferred and that unauthorized access is prevented.
