Creates a `DiffieHellman` key exchange object and generates a prime of
`prime_length` bits using an optional specific numeric `generator`.
If `generator` is not specified, the value `2` is used.

### crypto.createECDH(curve_name)

Creates an Elliptic Curve Diffie-Hellman (`ECDH`) key exchange object using a
predefined curve specified by the `curve_name` string. Use
[`crypto.getCurves()`][] to obtain a list of available curve names. On recent
