How do I use the gpg command line with Windows?
If you want to use GnuPG with the Windows Command Line, there are two methods: The easy way and the hard way. The easy way is to configure windows as shown here. This will enable you to open the command line by hitting START > RUN > cmd then just typing the gpg command (for example “gpg –help”). The hard way is that you need to move any file you are working with into the GnuPG directory, then navigate to the particular directory in DOS. This is time-consuming and extremely frustrating if you make a single mistake. So please, take my advice and do it the easy way. This configuration will take 30 seconds of your time and will save you twice that amount for each command you type.
