Create CSR and Install Certificates to Cerberus FTP Server

You can use our OpenSSL CSR Wizard along with OpenSSL to create the CSR and private key needed for your Cerberus FTP server. The CSR wizard can be located here: https://www.digicert.com/easy-csr/openssl.htm

Once you fill out the form and generate the command, you will copy and paste it in to OpenSSL, which will output a CSR file and a key file. In the example image below, the CSR and private key files are created in “C:\\OpenSSL-Win32\\bin”. You can go to that location to retrieve the CSR and private key.

You will use the CSR to place the order for the certificate (select “Other” as the server software), while you will want to hang on to the private key for the installation.

Once you receive the .zip containing the certificate files, extract the “certs” folder somewhere on your server. We will be combining the files you received in to a .pem format. To create the .pem file, you can reference our .PEM instructions:

With a text editor (such as wordpad), copy and paste the entire body of each certificate into one text file in the following order:

  1. The Primary Certificate - your_domain_name.crt
  2. The First Intermediate Certificate - DigiCertCA.crt
  3. The Second Intermediate Certificate(if a 2nd intermediate cert is supplied) – DigiCertCA2.crt
  4. The Root Certificate - TrustedRoot.crt
  5. The Private Key - your_domain_name.key

Make sure to include the beginning and end tags on each certificate. The result should look like this:

 

-----BEGIN CERTIFICATE----- 
(Your Primary SSL certificate: your_domain_name.crt) 
-----END CERTIFICATE----- 
-----BEGIN CERTIFICATE----- 
(Your First Intermediate certificate: DigiCertCA.crt) 
-----END CERTIFICATE----- 
 -----BEGIN CERTIFICATE----- 
(Your Second Intermediate certificate (if applicable): DigiCertCA2.crt) 
-----END CERTIFICATE----- 
-----BEGIN CERTIFICATE----- 
(Your Root certificate: TrustedRoot.crt) 
 -----END CERTIFICATE-----
-----BEGIN RSA PRIVATE KEY----- 
(Your Private Key: your_domain_name.key) 
-----END RSA PRIVATE KEY----- 

Save the combined file as your_domain_name.pem. Your .pem file should be ready for use.

You will now want to open Cerberus Ftp Server and navigate to Configuration, Server Manager, then click on Security in the left column.

If Enable SSL/TLS isn't already checked, then check it now.

In the Certificate field and Private Key field, browse to the .pem file you just created (use the same file for both fields).

Cerberus installation

The SSL certificate should now be ready for use.
