I enjoy espionage fiction, in film, books and on TV. It’s a pure escape from reality, which is not to say that I don’t learn from it. Take, for example, “tradecraft,” the label for all those spy tricks. I know how to follow someone, how to lose a follower, how to use a dead drop and how to change my identity and disappear.
Here’s how to communicate secretly and securely with one or more other people: Create an email account with an online service, like Gmail or Yahoo. You and your associates know the log in ID and the password. You write messages but you don’t send them; instead, you save them as drafts. Your associate reads the drafts when they log into the account and permanently deletes the messages. Nothing is ever transmitted and, even if the account is hacked, there’s nothing there to read.
Happy to share something so useful.
