The file is the “Win32_OpenSSL” and it will have some version number added at the end of the file. You can download the Windows install of Open-SSL from. To convert a PFX file to a PEM format requires the Open SSL tools which are free and open source. The SSL keys are typically in the form of a PFX file and you will need to convert them to a PEM/KEY format and strip off the encryption that is protecting the private key as WireShark will not read the private key if it is encrypted. Remember – you are viewing consumer’s private data and this should be treated with protection and respect. Using a private key to decrypt SSL traffic should only be done to debug application problem.

This blog entry will outline the steps to decrypt SSL traffic.

If you have access to the private key, Open SSL and WireShark installed then it is possible to decrypt the SSL traffic and see the traffic in the clear within WireShark. Debugging an application problem is very difficult when the network traffic is going via HTTPS (SSL).
