deriving private key from public key

[madhav-madhusoodanan]

1. elliptic uses bn.js. You can generate number with crypto.randomBytes and then check interval (0, n). Or you can use .getKeyPair()
2. new EC('curve25519').g.mul
3. You're right.

I'm just a beginner, so I might have missed some detail here, but does it imply that the private key is derivable from the public key? It was my understanding that the process should be near-impossible.
