ECDH is a variant of the Diffie-Hellman algorithm for elliptic curves. It is actually a key-agreement protocol, more than an encryption algorithm. This basically means that ECDH defines (to some extent) how keys should be generated and exchanged between parties. How to actually encrypt data using such keys is up to us.
