Description

Letterlocking refers to the folding and securing any substrate (such as parchment or paper) to function as its own envelope. Letterlocking is part of a 10,000-year-old information security tradition, ranging from Mesopotamian clay bullae to Bitcoin paper wallets. Letterlocking was an everyday activity for centuries, across cultures, borders, and social classes, and plays an integral role in the history of secrecy systems as the missing link between physical communications security techniques from the ancient world and modern digital cryptography.
