WebAug 2, 2024 · Microsoft has no default implementation of the elliptic curve x25519. However their implementations of cryptographic Diffie Hellman objects allows us to define our own curve. Once we define our own curve to use (x25519) we can use Microsoft's ECDiffieHellmanCng implementation to import the curve, generate keys, and create … WebCrypto++ (also known as CryptoPP, libcrypto++, and libcryptopp) is a free and open-source C++ class library of cryptographic algorithms and schemes written by Wei Dai. Crypto++ has been widely used in academia, student projects, open-source, and non-commercial projects, as well as businesses. [1]

If I wasn't mistaken, there can be atmost 2 PK corresponding to 1 SK in x25519, depending on whether the implicit y-coordinate is internally positive or negative. As for ECDH on the other hand, the mapping is 1:1. greenwich university moodle
