WebJan 7, 2024 · In this article. Providers associated with Cryptography API ( CryptoAPI) are called cryptographic service providers (CSPs) in this documentation. CSPs typically implement cryptographic algorithms and provide key storage. Providers associated with CNG, on the other hand, separate algorithm implementation from key storage. WebDiffie-Hellman key exchange with randomly selected keys produces a shared secret that is random in the statistician's sense, but its output is not uniformly distributed. So to use this secret as a symmetric key you pass it through some KDF.

This Recommendation specifies key-establishment schemes based on the discrete logarithm problem over finite fields and elliptic curves, including several variations of Diffie-Hellman and Menezes-Qu-Vanstone (MQV) key establishment schemes.

WebIn Diffie-Hellman, computations occur modulo a big prime p, and the resulting shared secret is an integer modulo p, i.e. a value ranging from 0 to p-1. This value has some "structure" so you should not truncate it blindly. The "safe" way is to apply a hash function on an encoding of that value, for instance SHA-256.
