Install an SSL Certificate on a FileZilla server

This guide will show you how to install an SSL Certificate on a FileZilla server.

Warning:Filezilla servers are not able to see more than 2 Intermediates.

Step 1. First you will need to generate a private key and CSR using OpenSSL.
Step 2. Here are the files you will need to collect: mydomain.crt, mydomain.ca-bundle, and mydomain.key. Be sure that they are all located in the same directory.
Step 3.

Start up the command prompt. Then you will need to enter the following command:

On Windows machines: copy mydomain.key + mydomain.crt + mydomain.ca-bundle mydomain_FZ.crt
On Linux machines: cat mydomain.key + mydomain.crt + mydomain.ca-bundle > mydomain.crt

Step 4.

As a result, you should get a file. Open it up in a plain text editor and you should see something that looks like this:

-----BEGIN RSA PRIVATE KEY-----
$TEXT
-----END RSA PRIVATE KEY-----

-----BEGIN CERTIFICATE-----
$TEXT
-----END CERTIFICATE-----

-----BEGIN CERTIFICATE-----
$TEXT
-----END CERTIFICATE-----

-----BEGIN CERTIFICATE-----
$TEXT
-----END CERTIFICATE-----

Step 5. On your FileZilla server, open the Options window. Make your way to the SSL/TLS settings and reference the file that you have just made in the Private Key and Certificate areas.
  Step 5
Step 6. Save it and continue by clicking OK.
Step 7. Stop your server, then start it up again.

Your server should now be able to make TLS connections.
