mkryptor SERVER installation guide

Last Updated: Nov 22, 2013 03:46PM GMT

mkryptor version(s): 2.0

In this guide you'll learn how to install and configure the mkryptor service. To learn how to get mkryptor working with your mail server or email client, see the additional guides in step 4 for the relevant server/client package.


Step 1 - Download mkryptor

If you haven't already downloaded the mkryptor installation package, please download from http://www.freshskies.com/downloads.aspx.

NOTE: You will need to log into your fresh skies account to access the downloads. If you do not already have a fresh skies account, you can register for free.
NOTE 2: There are 32bit and 64bit versions of the installer available. Be sure to select the correct file for your system.

Step 2 - Run the installer

  • Once you have downloaded the mkryptor setup .EXE file, double-click on it to run the installer.
Note: The installer will first check that you have all prerequisites installed, such as .NET Framework 4 and Visual C++ Runtime. If these prerequisites are not found you will be prompted to install them before the installation can continue.
  • You'll be presented with a standard windows installer interface:
Installer welcome
  • Click Next to begin the installation
  • Choose the location that you want the mkryptor program files installed to
    • It is reccommended to accept the default location
Select install location
  • Click Next to continue
  • Agree to to EULA and click Next again

Ready to begin
  • Click Next to begin the installation
Note: The rest of this guide assumes that this is the first time that you have installed mkryptor. If you are upgrading or reinstalling then the installer will use your existing license / configuration. Don't forget to re-start the service after install completes.
  • After a short time the mkryptor configuration manager will open.
  • The first thing that the configuration manager does is check for a license. As this is the first time that you have installed mkryptor, it will not yet have a license, so a prompt will pop-up to remind you that you must either enter a license key or start a free trial.
Click OK to dismiss license reminder
  • Click OK to continue
You can now either enter your license key (if you have already purchased mkryptor), or you can start a free 30 day trial. Select the option that applies to you from the options below:
  1. I have a license key
  2. I would like to start a free 30 day trial

To enter a license key

If you have already purchased mkryptor then you will have been issued with a license key. If you have forgotten your license key then you can find it in the My Licenses page in your Fresh Skies account, or by contacting your reseller.

Follow the steps below to assign your license to mkryptor:
  • ​Click the 'Enter License Key' button on the About tab
  • A box will pop-up for you to enter your license key into:
  • Enter your key in the box and press submit
  • If the license key was correct then you should get a confirmation prompt similar to below
  • Click Yes to continue
click yes to continue
  • ​You can now skip to Step 3
NOTE: License keys can only be used on a certain number of machines (depending on number of seats purchased). If you have no more installs available then you may need to purchase an additional server license. You can do this from the license management screen under My Licenses on the fresh skies website, or by contacting your reseller


To start a free trial:

  • ​Click the 'Get Trial License' button on the about tab
Click Get Trial License
  • An account login box will open.
  • Enter the login details for your fresh skies account (if you have not registered for a fresh skies account already, then click either the 'Forgotten Password / Register' link, or the fresh skies logo)
  • Click OK to connect to the Fresh Skies license server.
  • mkryptor will automatically download a day trial license and show the following prompt:
  • Click Yes and the license will be installed automatically.
  • The About tab will show the license details, including it's expiry date.
NOTE: If for any reason mkryptor is unable to retrieve the trial license automatically, contact support.

Step 3 - Basic settings

Before you can start the mkryptor service, there are a few minimum settings that you need to make. Namely the Admin Email address. This is the email account that error reports will be sent to, as well as the address used when sending notifications to users/recipients.

There are also plenty of other settings that you can make to customise mkryptor to your needs (See 'mkryptor configuration manager help') but for the purposes of this tutorial, we'll concentrate on the minimum settings to get started.
  • Once you've installed your license, click on the General tab
  • Fill in the 'Administrator Email' section.
  • Click Save
  • mkryptor will check all settings and attempt to send an email to this address. If successful then you have configured mkryptor.
NOTE: Due to the varying and complex nature of email systems and their configurations it is possible that things won't work first time. If mkryptor can determine the issue then it will prompt you with details on how to fix.

If mkryptor sends the welcome message successfully, but you do not receive it then check your junk/spam settings. It is important that you can receive mkryptor administrative messages.

If mkryptor is unable to contact your mail server, you can set-up routes on the Mail Out tab. There are 2 default routes, External (all outgoing mail to end-users) and Internal (Secure Replies, notifications to senders and administrative alerts)
  • If all the settings are OK you'll get a notification pop up to say that the installation has been a sucess.
  • Click OK to dismiss
  • You'll next be prompted to start the mkryptor service.
  • Click Yes, to start mkryptor
  • The service should start and the service status indicator at the bottom-left of the configuration manager should turn green.

mkryptor is now installed and running. You can either further customise your setup, or click the Exit button and move on to the next step.

Step 4 - Configuring mkryptor as your outbound gateway

Once you have the mkryptor service installed and configured, you now need to start sending messages through it. There are numerous guides on this site showing you the best way to achieve this with a variety of different mail servers / clients. See the below list for the most popular, or follow our generic guide. If you'd like us to add a guide for a particular server / client, please let us know

Product-specific guides:


Generic guide

Sever installations:
  1. Find the option in your mail server to deliver all outbound mail to an SMTP gateway or 'Smart Host'. 
  2. Set the gateway/smart host as the IP address / host name of your mkryptor service installation

Local (desktop) installations:
  1. It is recommended to set mkryptor to run on port 2525, as some desktop anti-virus products interfere with services running on port 25.
  2. In the mkryptor config manger Mail Out section, set the host, username, password, etc to your normal SMTP server
  3. In your email client application, set your SMTP server settings to point to mkkryptor (e.g., localhost, port 2525).

Step 5 [Optional] - Configure mkryptor SATELLITE service for secure replies

By default, mkryptor SERVER comes configured to use the CLOUS Basic reply service. While this does allow you to receive secure replies straigh out the box, it is fairly limited in features. It is recommended that you configure your mkryptor SERVER to use one of the alternative satellite options.

See here for a comparison of the different satellite options and how to to configure them

Step 6 - All done

You have now completed the installation of mkryptor. All that remains is to start sending mkrypted messages. The user guides can be found at the below link. It is recommended that you distribute the guide to all your staff/colleagues that will be using mkryptor.
