31 July 2017 IIS, SSL, OpenSSL, crt, pfx, key Robert Muehsig

The requirements are simple: You will need the .cer with the corresponding .key file and need to download OpenSSL.

If you are using Windows without the awesome Linux Subsystem, take the latest pre-compiled version for Windows from this site.

Otherwise with Bash on Windows you can just use OpenSSL via its “native” environment. Thanks for the hint @kapsiR

After the download run this command:

   openssl pkcs12 -export -out domain.name.pfx -inkey domain.name.key -in domain.name.crt

This will create a domain.name.pfx. As far as I remember you will be asked to set a password for the generated private .pfx part.

If you are confused with .pfx, .cer, .crt take a look at this nice description blogpost.

Hope this helps!
