19 de jan. de 2018 · Algorithms Explained: Diffie-Hellman. by Pyler January 19th, 2018. By arriving here you’ve taken part in a Diffie-Hellman key exchange! (Or at least a variant). Diffie-Hellman is a way of establishing a shared secret between two endpoints (parties). The mathematics behind this algorithm is actually quite simple.
Scambio di chiavi Diffie-Hellman. Lo scambio di chiavi Diffie-Hellman (in inglese Diffie-Hellman key exchange) è un protocollo crittografico che consente a due entità di stabilire una chiave condivisa e segreta utilizzando un canale di comunicazione insicuro (pubblico) senza la necessità che le due parti si siano scambiate informazioni o si ...

Generating Symmetric Keys with Diffie-Hellman. The result of the Diffie-Hellman Key Exchange is both parties have an identical Shared Secret. However, the shared secret itself should not be used directly as a Symmetric Key. Instead, it should be used as a seed value, from which to derive any amount of required symmetric keys.
If you are using a symmetric cipher, like the Caesar cipher or AES, then the key must be kept secret and no one except the sender and receiver should be allowed to see it. If you are using public key cryptography then you will have two keys: a public key and a private key. Everyone in the world should be allowed to see your public key, but you ...
