WebAug 6, 2024 · The Crypto++ library uses Andrew Moon's constant time ed25519-donna. The curve25519 gear appears to be like most other comparable public key objects in the Crypto++ library but it is mostly a facade. The Crypto++ classes are just wrappers around Moon's code that present some of the expected interface for callers. 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 …
