Red Army soldiers in WWII folded their letters in a triangular fashion -- not the American football fold -- as a way to deal with a paper shortage and to comply with censorship rules. In Victorian Britain, this was called a cocked hat letter. #origami @origami #letterlocking

Letter Locking FAQ

#LetterLocking

Letterlocking is the ancient art of folding letters or envelopes so they can’t be opened without damaging the letter, or at least making it obvious the message has been tampered with. Used from medieval times to almost the modern day, with different techniques used in various countries, this art is quite complex and fascinating

This website provides diagrams and videos of dozens of examples, including those used by famous historical figures

early end to end encapsulation

letterlocking was used as a tamper-evident closing of a letter by using folds, cuts and glues to make it difficult to snoop undetected

Not really encryption, but still a lot more work than GPG encrypting something
