The Greatest Cryptographic Invention?

Last week I set up four quizzes on the greatest cryptographic invention, and which ran for around one week. In the first poll, the mighty Diffie-Hellman method won by a long way, against the Fiat-Shamir heuristic (and which converts an interactive proof into a non-interactive proof. With zkSnarks, we have the opportunity to prove the knowledge we have, without giving away our secrets. With the Schnorr signature, we get the signing method that is used in EdDSA.

For the second poll, it was a little closer, but where AES Symmetric Key encryption gained over half of the votes, and beating lattice cryptography and DSA/ECDSA signatures. The usage of MD hashing did not fair well:

In the third poll, there was a tie between Shamir Secret Shares (SSS) and the Lucifer cipher (as used with DES and 3DES). Pairing-based cryptography did fairly well with 20% of the vote, but the Pederson Commitment lagged back in last place:
