Certdog Windows Installation

The following steps outline the steps required to install the Certdog on a single system

If the pre-requisites are in place, the entire installation should not take more than 10 minutes

If you don’t want to read any details right now and just want to quickly download to try things out - see the Quick Installation Guide


The system may be installed on the following operating systems:

  • Windows Server 2016

  • Windows Server 2019

  • Windows 10 1

The following components are required:

  • .NET 4.8 Runtime

  • Visual C++ Runtime (this will be installed by the installer if not present)

You must have local Administrator privileges on the system

1. Download the Installer

Contact support for a download link. If you have an FTP account it will be placed in your download area

1.1 Verify the download

To verify the downloaded file, perform the following operations:

Open a command prompt or PowerShell window and navigate to the download location e.g.


At the prompt type:

certutil -hashfile sha1

Or, if you wish to produce the longer SHA-256 hash, type:

certutil -hashfile sha256


C:\temp\downloads>certutil -hashfile sha256
SHA256 hash of c:\Users\myname\Downloads\
CertUtil: -hashfile command completed successfully.

Compare the hash value produced with the following checksums:

SHA1: e759db6cb4e3f66656c0c1b120630295f1e2cd55

SHA256: eeaab3196237b390e861cf5ab3c2abab51f70ba1d63069a40d97bc9852dc4e83

If they differ, the download is corrupt or has been altered. Attempt the download again, the file sizes should be over 100Mb. If hashes still don’t match please contact

1.2 Unzip

Unzip this to a location on the target machine. You may wish to create a folder beneath C:\Program Files such as:

C:\Program Files\Krestfield

But you can also create a folder anywhere on the file system (e.g. F:\apps)

Unzip the contents of the download to this folder. This should result in a directory structure such as:

C:\Program Files\Krestfield\certdog or F:\apps\certdog

Open a PowerShell prompt as Administrator and navigate to this folder e.g.

Windows PowerShell
Copyright (C) Microsoft Corporation. All rights reserved.

PS C:\WINDOWS\system32> cd "C:\Program Files\Krestfield\certdog"
PS C:\Program Files\Krestfield\certdog>

Run dir and check the file structure looks something like the following:

    Directory: C:\Program Files\Krestfield\certdog

Mode                 LastWriteTime         Length Name
----                 -------------         ------ ----
d-----        06/01/2021     17:46                bin
d-----        05/01/2021     16:01                config
d-----        08/01/2021     11:27                install
d-----        07/01/2021     15:22                java
d-----        06/01/2021     15:48                tomcat

If you don’t see the install directory, the unzipping process may have failed. Check that you have the correct permissions, then delete the certdog folder and attempt the unzip process again

2. Run the Installer

From the PowerShell prompt, navigate into the install directory and run the .\install.ps1 script:

PS C:\Program Files\Krestfield\certdog> cd install
PS C:\Program Files\Krestfield\certdog\install> .\install.ps1

(For the demo version run .\install-demo.ps1)

Note: If you see the message Do you want to run software from this untrusted publisher? type A to always run. The scripts are signed with a publicly trusted CA, but depending on your security settings, there may still be a requirement to recognise the signer

If your system does not have the Visual C++ Redistributable packages installed, this installer will begin. Complete this installation and when complete, return and re-start the .\install.ps1 script

If you do not have the .NET 4.8 Runtime installed, the installer will recognise this and end. Install the .NET 4.8 Runtime then restart the .\install.ps1 script

The installer will start and display some initial information. e.g.

Krestfield Certdog Setup Version 1.0

This script will install the Certdog system on this machine

Follow the instructions to install the system, noting the following:

  1. In the first instance it is recommended that you install all required components (including java and the database binaries). These files are installed in the local directory and if required, can easily be removed later

    I.e. when prompted with:

    Download java (y/n)? (Choose n if you have previously downloaded):
    Enter y

    and when prompted with

    Download the database binaries (y/n)? (Choose n if you have previously downloaded):

    Enter y

  2. You will be prompted to enter details and passwords for several accounts, these are discussed in the Accounts and Passwords section below

  3. You will be asked what interface you wish the system to be available on and the current available IP Addresses (as configured on your system) will be listed

    For a production system you should have an IP Address available which will be targeted via a DNS entry. For an initial test system the local loopback address ( can be used

There are many customisations and deployment options that can be applied including the separation of services across multiple machines, hosting on other containers, using shared databases and hosting fully or partially in the cloud. Contact support for more details

3. Verify the Installation

First, check the installation log files for any errors

  • installlog.out
  • installlog.txt

If no errors were shown during the installation these files should just contain audit information

From the PowerShell script, navigate to the ..\bin folder and type .\is-db-running.ps1:

PS C:\Program Files\Krestfield\certdog\install> cd ..\bin
PS C:\Program Files\Krestfield\certdog\bin> .\is-db-running.ps1
Database is running

The message Database is running should be seen

Then type, is-api-running.ps1

PS C:\Program Files\Krestfield\certdog\bin> .\is-api-running.ps1
API is running

The message API is running should be seen

If either the database or API are not running, see the Troubleshooting guide here

Next, open a browser and navigate to https://[Your IP Address]/certdog/ui

Where [Your IP Address] is the address chosen during the installation e.g.

You should see a warning such as:


This is because we have not yet configured a valid SSL certificate. For now, click Advanced then click Continue to (unsafe)

You should see the login screen:


Enter the username and password for the First Admin User that you provided during the installation and click Login

You should be logged in OK. The initial view will be Certificates, but at this stage there are none to show

A successful login indicates that the installation was completed OK

4. SSL Configuration

By default an a test SSL certificate protects the system using the default IP address

This certificate will not be trusted by your system. You will see warnings when accessing the application via browser and REST API calls may fail

For test purposes you may continue to use the provided SSL certificate. To enable trust double click the following certificate:

[Install Dir]\config\sslcerts\dbssl_root.cer


Click Install Certificate… and select Local Machine


Select Place all certificates in the following store and browse to Trusted Root Certification Authorities, click Next and then Finish

Finally, click Yes

If you now close the browser, re-open and navigate to the warnings should be gone

Note: This is a test certificate and should not be trusted in a production environment. You should still continue to create a valid SSL certificate as described here

Accounts and Passwords

During the installation you will be prompted for the following details:

  • The Database User Admin Account
    • This is the main database administrator account and is used by the installer to create the other initial database accounts required by the system
    • You will not normally need to use this account on a day-to-day basis but you must retain the details (username as displayed and the password you enter)
    • If you wish to manually configure the database later (for example if all user accounts were lost), these credentials will be required
  • First Admin User
    • This is the first user that will log into the system, as an administrator. This will normally be your account
    • As well as a username and password, you will be required to enter an email address. All certdog user accounts require an associated email address to which notifications from the system may be sent
  • Master Password
    • This account is used as the top level protection for other accounts. It is not stored in the clear on the system
    • You must enter this password when installing the Application Service
    • Once entered, it should not be required again for this system but should be stored securely. If you start the application manually (not via the windows service) or wish to host the application on another container (e.g. on a shared Tomcat service), this password will be required

Windows Services

Application Service

This service will be installed by the install script but can also be installed manually by running the .msi installer separately. This .msi installer is located here:

[Install Folder]\install\bin\InstallCertdogService.msi

This service starts and stops the system

In the services snapin, this service is called Krestfield Certdog Service

AD Certificate Services Agent

This service interfaces with your Microsoft ADCS instance. More details on this service can be found here

In the services snapin, this service is called Krestfield Adcs Driver

  1. Windows 10 can not host the ADCS Driver. This component must be installed on a Server based operating system. See the ADCS Driver documentation for more information
