How to Make Your Own Lamport Parachute from Common Household Materials.

The thought began, as many good things begin, in #trilema. Users of the WOT, of V, and other systems where your cryptographic identity is wholly in your own hands1 live with a certain risk of “cryptographic death” – i.e. the compromise of one’s signing key. A conscientious user of public key crypto might keep the […]
