How to Get Host Key from SFTP Server FileZilla?

Welcome, Dev! In this article, we’ll be discussing the process of obtaining a host key from an SFTP server using FileZilla. The host key is an essential component of securing file transfers between servers and clients. In this guide, we will be taking you through the step-by-step process of obtaining the host key for your SFTP server. So, let’s get started!

What is a Host Key?

Before we dive into the process of obtaining a host key, let’s first understand what a host key is, and why it’s important. A host key is essentially an identification key that is unique to each server, and which is used to secure communication between the server and clients. It helps to ensure that data transferred between the two is not tampered with, and that the server’s identity is verified.

The host key is generated by the server when it is first set up, and it is typically stored in the server’s configuration files. When a client attempts to connect to a server, the host key is provided to the client, and the client verifies its authenticity before establishing the connection.

Now that we have a basic understanding of what a host key is, let’s move on to the process of obtaining it from an SFTP server using FileZilla.

Step-by-Step Guide to Obtaining Host Key from SFTP Server FileZilla

Step 1: Download and Install FileZilla

The first step in the process is to download and install FileZilla on your computer. FileZilla is a free, open-source FTP client that supports SFTP, FTPS, and FTP protocols. It’s available for Windows, Mac, and Linux, and can be downloaded from the official FileZilla website.

Step 2: Connect to Your SFTP Server

Once you have installed FileZilla, the next step is to connect to your SFTP server. To do this, you will need your server’s hostname or IP address, as well as your SFTP login credentials. Open FileZilla and click on the “File” menu. Select “Site Manager” from the dropdown menu, and then click on the “New Site” button.

Enter the hostname or IP address of your SFTP server in the “Host” field, and then select “SFTP – SSH File Transfer Protocol” from the “Protocol” dropdown menu. Enter your SFTP login credentials in the appropriate fields, and then click on the “Connect” button to connect to your SFTP server.

Step 3: Obtain Host Key

Once you have established a connection to your SFTP server, the next step is to obtain the host key. To do this, click on the “Edit” menu in FileZilla, and then select “Settings” from the dropdown menu. In the Settings dialog box, click on the “SFTP” option on the left-hand side of the window. You should now see a list of known host keys for your SFTP server.

If you do not see any host keys listed, click on the “Add keyfile” button and navigate to the location on your computer where the host key is stored. If you are unsure of the location of the host key, consult your server administrator or hosting provider for assistance.

Once you have added the host key, FileZilla will verify its authenticity and add it to the list of known host keys. You can now use this host key to securely transfer files between your SFTP server and your client.
