Manually unbreakable cryptography

elseif has not written about this yet · John D. Cook describes it this way

Suppose you were able to go back in time, to an era before computers, and give someone contemporary cryptography. Encryption methods that are essentially unbreakable now would certainly be unbreakable then. But there’s a catch: not only do attackers not have computers, neither do users. Manual cryptography If you told someone about RSA encryption, for […] The post Manually unbreakable cryptography first appeared on John D. Cook.
