I really should say payments world. Banks use PGP regularly for file transfer (bank statements and the like). Payment processors use PGP for settlement statement transferring. The page I linked uses PGP for application layer encryption. If you poke around the reference page[0], you see a bunch of different specs that 3rd party platforms can build against and be hooked up into Google as a form-of-payment (ie: used by people to pay for Ads, Play, Cloud, etc...). We encrypt each message passed between Google and a payment process with PGP. These are just normal server-to-server calls over HTTPS with JSON payloads (with the json payload being PGP encrypted).
