Derek Caelin is writing a book<p>I've been reading people's mail.</p><p>They are the letters of Abigail and John Adams from 1775, so historians tell me this OK?</p><p>John is *extremely* cautious in writing. Lots hints and promises to say more in person. This was wise, because a lot of the letters of the Continental Congress were intercepted by the British at the time.</p><p>This all makes me wonder what the state of <a href="https://social.coop/tags/cryptography" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>cryptography</span></a> was in those days, and whether the Adams could have adopted any good encryption measures.</p><p><a href="https://social.coop/tags/history" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>history</span></a></p>

Flipboard Art & Photo Desk<p>35 years ago, Jim Sanborn presented the cryptographic sculpture Kryptos to the Central Intelligence Agency in Langley, Virginia. Made from copper, granite, quartz and petrified wood, it has four sections, each of which holds a message in code. Over the years, three of the sections have been solved — by CIA code breakers, a California computer scientist, and the National Security Agency. Now, 79-year-old Sanborn says he's going to auction off the solution to the final message, with the company arranging the sale estimating a winning bid between $300,000 and $500,000.
