Typewriters and Security
If it’s good enough for Vladimir…
At the moment, the most secure and, at the same time, usable, method of creating, sharing and storing information is to write it up on a manual typewriter and store it in a locked filing cabinet or send it in an envelope via the good old Royal Mail. This is not a perfect system. It can be vulnerable to burglars or to Police Officers armed with a search warrant, but it may be better than anything else that is available to the general public, or, for that matter, to corporations or government agencies that truly wish to protect their secrets.
