be. The values point to the internal representation of the public key and
private key values. This memory should not be freed directly.
-The public and private key values can be set using DH_set0_key(). The public
-key must be non-NULL the first time this function is called on a given DH
-object. The private key may be NULL. On subsequent calls, either may be NULL,
-which means the corresponding DH field is left untouched. As for DH_set0_pqg()
-this function transfers the memory management of the key values to the DH
-object, and therefore they should not be freed directly after this function has
-been called.

DH_set_flags() sets the flags in the B<flags> parameter on the DH object.
Multiple flags can be passed in one go (bitwise ORed together). Any flags that
