What is it about tweetnacl that you find difficult to use? It has crypto_scalarmult, which takes a point and an integer and outputs the result. It’s hard to imagine how it could get much simpler than that.

I've been trying to search for general Curve25519 and Ed25519 libraries where I can just do add and scalar multiply as well as hash messages to points. The best library I've come across so far is tweetnacl, which has the add and scalar multiply operation for Ed25519, but it's a bit difficult to use, and I end up modifying the library to do subtraction of points.
