Using GPG from behind proxies.

I have struggled a lot to get the GPG working inside corporate firewalls. It is so cumbersome to set the tools to automatically request keys from keyserver for signature validations. Finally found the magic options for doing this from behind HTTP proxy. Just keeping this command here for reference.

gpg --keyserver x-hkp://pgp.mit.edu --keyserver-options honor-http-proxy --recv-key 060C80C2
