Hi Frank. Check out Adam Langley's curve25519-donna. It has no external dependencies and looks pretty straightforward to use: https://github.com/agl/curve25519-donna
There's also libsodium which has Ed25519 support: https://github.com/jedisct1/libsodium On Wed, Jun 17, 2015 at 2:16 PM, Frank Wang <[email protected]> wrote: > Hi, > > I am working on a research project at MIT, and I need to use elliptic > curves (or a group where DDH is hard, but elliptic curves seem like the > best way to go) to implement a cryptographic scheme.
