Use the libsecp256k1 style ECDH shared key generation #6

Closed cdecker closed 7 years ago

cdecker commented 7 years ago

The spec says that we use the libsecp256k1 style ECDH, which uses the full compressed pubkey from the scalar multiplication which is then hashed. This is in contrast to the btcsuite implementation which was only using the hashed X-coordinate.
