How to Read a PFX File

By Mitchell White

A PFX file is a digital certificate that's used to determine whether a device like a computer or Web server is authentic, that is, whether it is what it says it is. You can open a PFX file with the native program Microsoft Certificate Manager. This program is already installed on Windows computers, so you won't have to download anything new to use it.

Step 1

Click "Start" in Windows.

Step 2

Type "certmgr.msc" into the search box and press "Enter" to bring it up.

Step 3

Double-click on the PFX file in the Certificate Manager to open it.
