What Diffie-Hellman (DH) Group Should I Use

Is there any particular reason to use Diffie-Hellman over These are two distinct beast; although they share the same core mathematical operation and format for keys, they do different things in different ways. Diffie-Hellman is a key exchange algorithm, which is yet another kind of algorithm. Since the algorithms don't do the same thing, you could prefer one over the other depending on the usage context. ECDiffieHellmanCng Class (System.Security.Cryptography Alice and Bob create a key pair to use for the Diffie-Hellman key exchange operation. Imports the public/private keypair from an ECPrivateKey structure, replacing the keys for this object. (Inherited from ECDiffieHellman) ImportEncryptedPkcs8PrivateKey(ReadOnlySpan

Diffie-Hellman algorithm. The Diffie-Hellman algorithm is being used to establish a shared secret that can be used for secret Alice and Bob compute symmetric keys Alice: ka = y^a mod p = 65536 mod 23 = 9 Bob: kb = x^b mod p = 216 mod 23 = 9 Step 7: 9 is the shared secret. Diffie–Hellman Key Exchange - Practical Cryptography for Diffie–Hellman Key Exchange (DHKE) is a cryptographic method to securely exchange cryptographic keys (key agreement protocol) over a public (insecure) channel in a way that overheard communication does not reveal the keys. The exchanged keys are used later for encrypted communication (e.g. using a symmetric cipher like AES). What Diffie-Hellman (DH) Group Should I Use

### The technique is notable because it puts a backdoor—or in the parlance of cryptographers, a "trapdoor"—in 1,024-bit keys used in the Diffie-Hellman key exchange. Diffie-Hellman significantly

Encryption Algorithms Explained with Examples How does Diffie-Hellman work? Diffie-Hellman is what's called a key exchange protocol. This is the primary use for Diffie-Hellman, though it could be used for encryption as well (it typically isn't, because it's more efficient to use D-H to exchange keys, then switch to a (significantly faster) symmetric encryption for data transmission). How RSA and the Diffie-Hellman Key Exchange Became the
