May 18, 2012 For Cerberus, you only need the client’s SSH public key generated by PuttyGen. Cerberus does not need the client’s private key. That is used exclusively by the client. The Security page of the Server Manager is just for configuring the server key. Open the Cerberus FTP Server User Manager. The default page is the Users tab. Select the user account that you wish to configure from the Cerberus Users account list. Select the Authentication button. Select the Public Key Only, Public Key and Password or Password or Public Key radio option. Feb 16, 2017 In today’s video we’ll teach you how to set up SFTP public key authentication on JSCAPE MFT Server. Public key authentication allows you to enforce 2 factor authentication to users connecting.
Use these instructions to use OpenSSL to create your CSR (certificate signing request) and then, to install your SSL and intermediate certificates.
Jun 04, 2019 Where do I get SSH host key fingerprint to authorize the server? Also note that the host key fingerprint is generated from a public key part of the host key only. So it is not secret and can be safely sent over unencrypted (yet trusted) communication channels. Connecting to FTP/SFTP server; Generate Session URL. To allow the use of RSA / DSA key files with Filezilla, you'll need to download two more tools from PuTTY: Pageant and (assuming your key file isn't already in PPK format) PuTTYgen. Generate ssh key. Filezilla can use existing ssh key, but cannot generate ssh key itself. You can generate ssh key with putty or openssh.
To create your CSR, see Cerberus FTP Server: Using Open SSL to Create Your CSR.

Cerberus FTP Server: How to Generate a CSR Using OpenSSL
If you prefer, you can build your own shell commands to generate your Cerberus FTP Server certificate signing request (CSR).
Login to your server via your terminal client (ssh).
At the prompt, enter the following command, making sure to replace server with the name of your server:
openssl req –new –newkey rsa:2048 –nodes –keyout server.key –out server.csrThis starts the process for generating two files:
The Private-Key file for the decryption of your SSL Certificate.
A Certificate Signing Request (CSR) file, used to apply for your SSL Certificate.
When you are prompted for the Common Name (domain name), enter the fully qualified domain name (FQDN) for the site that you are securing.
Note: If you are generating a Parse.com CSR for a DigiCert® Wildcard Plus™ Certificate, your common name should begin with an asterisk (i.e. *.example.com).
When you are prompted, enter your organizational information beginning with your geographic information.
Note: You may have default information set already.
This creates your OpenSSL .csr file.
Open the .csr file with a text editor.
Then, copy the text, including the -----BEGIN NEW CERTIFICATE REQUEST----- and -----END NEW CERTIFICATE REQUEST----- tags, and enter it into the DigiCert order form.
Note: During your DigiCert SSL Certificate ordering process, make sure that you select Apache when asked to Select Server Software. This option ensures that you receive all the required certificates for Cerberus FTP Server SSL Certificate installation (SSL and Intermediate Certificates).

After you receive your SSL Certificate from DigiCert, you can install it.
2. Cerberus FTP Server: Install Your SSL Certificate
After receiving your SSL Certificate, you need to install the SSL and Intermediate Certificates on your Cerberus FTP Server.
If you have not yet created a Certificate Signing Request (CSR) and ordered your certificate, see Cerberus FTP Server: Using Open SSL to Create Your CSR.
To install and configure your SSL Certificate, do the following:
Create a .pem file with the SSL and Intermediate Certificates.
See How to Create a .pem File with the SSL and Intermediate Certificates.
Install your .pem formatted SSL Certificate file.
See How to Install Your SSL Certificate File.
Cerberus Ftp Api
i. How to Create a .pem File with the SSL and Intermediate Certificates
Once you receive the .zip containing the certificate files, extract the “certs” folder somewhere on your server.
You will be combining the files you received in to a .pem format.
Open a text editor (such as WordPad) and paste the entire body of each certificate into one text file in the following order:
- The Primary Certificate - your_domain_name.crt
- The Intermediate Certificate - DigiCertCA.crt
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 Intermediate certificate: DigiCertCA.crt)
-----END CERTIFICATE-----Save the combined file as your_domain_name.pem.
The .pem file is now ready to use.
ii. How to Install Your SSL Certificate File
Log into your Cerberus FTP Server console.
In the Cerberus FTP Server console, on the Summary tab, in top-menu, click Configure.
In the Server Manager window, in the sidebar menu, click Security (gold lock).
On the Security page, under Security, check Enable SSL/TLS.
Next under Server Key Pair, do the following:
Certificate: Click the folder to browse for and select your SSL Certificate .pem file you just created (i.e. your_domain_name.pem). Private Key: Click the folder to browse for and select your private key .key file (i.e. your_domain_name.key). Then, click OK.
You have successfully installed and configured your Cerberus FTP Server SSL Certificate.

The first time a user connects to your SSH or SFTP server, his/her file transfer client may display an alert or notice indicating it doesn't recognize the server's fingerprint. What it's actually referring to is the server's SSH/SFTP key fingerprint, an important security feature that helps users and client applications authenticate SSH/SFTP servers. This post explains how it's used.
Importance of server authentication
Server authentication is a process that allows client applications to validate a server's identity. In other words, it helps a client determine whether it's really connecting to the server it intended to connect to. If the server fails the SSH host key authentication process, then it's possible that the server's host key was simply changed by the admin. That's not a big problem.
However, it could also mean that someone has carried out a spoofing or man-in-the-middle attack and, therefore, the client is likely on the verge of connecting to a malicious server. Now, THAT is a serious problem.
If a user unknowingly logs in to a malicious server, who ever has control of that server could easily acquire that user's login credentials and then use those credentials to gain access to the legitimate server. Secondly, if the unwitting user uploads files to the malicious server, those files will surely fall into the wrong hands. Lastly, if a user downloads files from the server, that user could end up downloading malware.
Server authentication helps prevent these from happening because if the authentication process fails, the client will be given an appropriate warning.

SSH / SFTP server autentication using fingerprints
How do you implement server authentication in SSH/SFTP? Theoretically, you can do this. As a server admin, you can furnish each user a copy of your server's public key. Public keys are supposed to be unique. Everytime a user connects to the server, the server can show the user its public key and the user can then compare that with his local copy. If they match, the user knows he's connecting to the right server.
There is however one problem with this method. Public keys are quite lengthy. So lengthy that it would be impractical for anyone to manually compare two copies. Your server authentication process will be time consuming.
A better way of carrying out server authentication when using SSH/SFTP is by inspecting the public key fingerprint. A fingerprint in this context is basically a hash function of a public key. Simply put, it's a shorter equivalent of the public key. If you're not familiar with how hashes work, I suggest you read the post 'Understanding Hashing' first.
Because fingerprints are much shorter than public keys, they're also much easier to inspect and compare even through the naked eye.
How to use public key fingerprints
The first time a user connects to your SSH/SFTP server, he'll be presented with your server's fingerprint. To verify, the user can contact you and you can then dictate to him your record of the fingerprint. If they match, the user can then store that fingerprint for future login sessions. Most SSH/SFTP clients allow users to save fingerprints.
Once a fingerprint is saved, the client can automatically look up that fingerprint every time it connects to an SFTP server. If a match is made, the client will know it's connecting to a server it had already connected to before.
It's therefore very important to make sure all fingerprints the client saves have already been manually verified. If you accept a fingerprint without verifying, especially if you're connecting to a remote server, you might end up storing a fingerprint of a malicious server.
How to obtain the fingerprint if you're an administrator
What if you're an admin but don't know what your server's fingerprint is? Don't look so surprised. These things happen you know. The quickest way to obtain it would be to login to your SSH/SFTP server from a locally installed client application, i.e. installed on the same machine as your server. That way, you can be absolutely sure you're safe from man-in-the-middle attacks.
If you're using Linux and have the built-in SSH client, make sure there is no 'localhost' entry found inside ~/.ssh/known_hosts file. Delete the entry if you find any before attempting the connection. The moment you connect, you'll encounter something like this:
Copy that fingerprint and save it where you can easily access it.
If your server runs on Windows or another GUI-based operating system, then you can install an SFTP client like AnyClient and connect to the server (again, locally). You should then see something like this:
Lastly, if this tool is available on your server (it's usually available on Linux), you may run the following command:
ssh-keygen -lf /path/to/public_key/pubkey_in_openssh_format.pub
In some SFTP servers, you'll have to export the public key in OpenSSH format for this to work. In JSCAPE MFT Server, go to Server > Key Manager > Server Keys. Select the server key, click Export > Public key.
Select the OpenSSH format and then click OK.
Once the public key is exported, you can then run ssh-keygen -lf on it likeso to reveal the fingerprint:
