Utiliser un certificat ssl .cer pour apache

Last time I did this, I found the instructions pretty easily on how to migrate SSL's from IIS to Apache. This time I found it hard to locate the documentation, so for my own lack of memory and when google fails you, here it is:

First we need to export the certificate from IIS into a pfx file. To do that:
Click Start->Run->type: mmc [enter]
Click ->'Console' -> `Add/Remove Snap-in'.
Click -> `Add' -> `certificates' snap-in and click on `Add'.
Select -> `Computer Account' -> click `Next'.
Select `Local Computer' and then click `OK'.
Click `Close' and then click `OK'.

In the menu for `Certificates' and click on the `Personal' folder.

Choose your certificate to export and select `All tasks' -> `Export'.
In the wizard, check the box to include the private key, continue until you have a .PFX file.

Move the Certificate to the machine Running Apache:

Now, we are going to use openssl to extract the private key, and the cert file.

    # Export the private key from the pfx file
    openssl pkcs12 -in iis.pfx -nocerts -out apache.key.pem
    # Export the certificate file from the pfx file
    openssl pkcs12 -in iis.pfx -clcerts -nokeys -out apache.cert.pem
    # ****This removes the passphrase from the private key so Apache won't
    # ****prompt you for your passphase when it starts
    openssl rsa -in apache.key.pem -out apache.key
