Installing your SSL Certificate / Web Server Certificate / Secure Server Certificate from ssl247.co.uk

Firstly when your issuance email arrives you will have two certificates in the email - your server certificate and a UTN chained certificate.

Copy your web server certificate into a text editor such as notepad and save as chain.crt.
You can ignore the UTN chained certificate for now, we will address this later.

Note: For Windows NT4.0, you must have at least Service Pack 4.0 or higher or Microsoft Internet Explorer 5.0.

1. Start the MS IIS Management Console and select your server.
2. Click on the Key Manager icon. Select your original key.
3. Select Install Key Certificate from the Key menu.
4. Choose yourdomain.crt file sent to you via email.
5. Type in your original key's password.
6. Click OK in the Server Bindings box. When you are prompted for bindings, add the IP and Port Number. "Any assigned" is acceptable if you do not have any other certificates installed on the web server. Note: Multiple certificates installed on the same web server will require a separate IP Address for each because SSL does not support host headers.
7. Select Commit from the Computers menu. Click Yes to commit all changes.

Backing up your key pair file

Unlike other files, key pair files (keypair = private key + certificate) cannot just be copied. To make a backup, you must Export to a Backup File. To restore your system, you must do an Import from a Backup File.

This process assumes identical web server configurations are used for exporting the key as well as for importing the key. So both servers must be IIS. You can't go from one type of server to another.

Exporting your key

• Open your Microsoft Management Console via the IIS Internet Service Manager.
• Click to open the Key Manager.
• Select the key to be exported.
• Select the Key menu and choose Export Key to a Backup File. Click OK in the Key Manager Warning box.
• Specify the destination for saving your key, press OK.
• Close your Key Manager and Management Console windows.

Please remember your password that was used to install your certificate. You will need this password if you ever need to recover your certificate through the import process.
