Create and apply a self-signed certificate – Windows 7/IIS7

Written by stevey on August 7th, 2011

Creating a self-signed certificate on Windows 7/IIS7 was quite a different experience and it took me more time to set it up and work correctly (in retrospect, it should have been easier as most of things can be configured with GUI tool). Anyway, I don’t want to repeat the pain and relearn how this is done, let me summarize the steps here to share with others and to help me find it easier in a rainy day:

  1. Open IIS7 (If IIS7 is not available from Administrative tools, go to Control Panel – > Programs – > Turn Windows Features On or Off.
  2. Click on machine node then double click on “Server Certificates” on the IIS pane
  3. Select “Create self-signed certificate” from the “Action” pane and give a friendly name such as “WcfSecure” in this case.
  4. Once the server certificate is created, view the certificate detail and write down the Thumbprint, something like ae 8f b2 b4 b0 b6 07 16 8e 73 51 35 38 cd 6b bb 7e 1f 12 d5, and remove the spaces to become ae8fb2b4b0b607168e73513538cd6bbb7e1f12d5, copy it to notepad for later use.
  5. Next, configured the Certificate to port, using VS2010 Guid tool to generate a GUID and run VS2010 Command prompt (must run as admin):netsh http add sslcert ipport=0.0.0.0:8080 certhash=ae8fb2b4b0b607168e73513538cd6bbb7e1f12d5 appid={0270078A-39C3-47E8-845C-07D904672C71}
  6. Created a website to use the certificate so that WCF Service can be hosted in https mode; to do that click on Sites node and right click ->Add Web Site ->Named it “WcfDemo” and assign to Port 444 (443 and 442 have already been taken)
  7. Assign the certificate to the new website by choosing Binding type “https”, and pick the certificate from the Certificate drop down; certificate is on machine or server level, so there could be multiple certificates and multiple site can use same certificate.
  8. Refer to MSDN article at http://msdn.microsoft.com/library/ff406125.aspx for more in-depth detail.

It is important to note, that In IIS7, whenever a new website is created, it automatically creates a new application pool named the same as website, in this case, WcfDemo is the new app pool. And it automatically defaulted to use .Net Framework version 2.0, so be careful to manaully change it to the version that your Wcf app is using, in my case, changed to .net 4.0. Pay attention to Identity; by default, the Identity uses ApplicationPoolIdentity, other options are LocalService, LocalSystem, NetworkService, these are under Built-in account dropdown; you can also use Custom account and use the Windows user account for the application pool identity. If sqlexpress database is used for storing Membership users and if the security mode is set to use Integrated Security=true, then the
Application pool identity must use Localsystem or an “An unsecured or incorrectly secured fault was received from the other party. See the inner FaultException for the fault code and detail.” error will throw when WCF client calls the Wcf Service from this website.

If, however, the sql database uses “SQL Server Authentication” mode and passes in a predefined username and password in the sql connection string, then you can leave the default ApplicationPoolIdentity alone.
