  3. DH_new_by_nid, DH_get_nid - get or find DH named parameters
  4. =head1 SYNOPSIS
  5. #include <openssl/dh.h>
  6. DH *DH_new_by_nid(int nid);
  7. int *DH_get_nid(const DH *dh);
  8. =head1 DESCRIPTION
  9. DH_new_by_nid() creates and returns a DH structure containing named parameters
  10. B<nid>. Currently B<nid> must be B<NID_ffdhe2048>, B<NID_ffdhe3072>,
  11. B<NID_ffdhe4096>, B<NID_ffdhe6144> or B<NID_ffdhe8192>.
  12. DH_get_nid() determines if the parameters contained in B<dh> match
  13. any named set. It returns the NID corresponding to the matching parameters or
  14. B<NID_undef> if there is no match.
  15. =head1 RETURN VALUES
  16. DH_new_by_nid() returns a set of DH parameters or B<NULL> if an error occurred.
  17. DH_get_nid() returns the NID of the matching set of parameters or
