Moving An SSL Certificate From Linux/Apache To Windows/IIS

In order to move an SSL cert from Apache to IIS, you must create a single PFX or P12 file from the .key and .crt files, and then import it on Windows. Here are the steps to doing so:

1. Run the following command from the shell:

openssl pkcs12 -export -out outputfilename.pfx -inkey keyfilename.key -in

It will prompt you to create a password…you’ll need to remember this password when you import it into IIS.

2. Copy the newly create pfx file to your Windows computer.

3. Open the IIS Managment Console, right click on the site and click Properties. Go to the Directory Security tab, click the Server Certificate button. Select “Import a certificate from a .pfx file”. The rest of the step should be pretty self-explanatory. Good luck!
