OK, Moritz, would you be so kind to give me a hint how to convert a key to =
an=20
MPI value?

I tried this:

  if (gcry_ac_key_pair_generate (hd, &keyPair, 1024, (void *)0))
  {
	...
  }
 =20
  privKey =3D gcry_ac_key_pair_extract (keyPair, GCRY_AC_KEY_SECRET);
  pubKey  =3D gcry_ac_key_pair_extract (keyPair, GCRY_AC_KEY_PUBLIC);

  char  key[2048];
  size_t keylen =3D 2048;
 =20
  if (gcry_mpi_print (GCRYMPI_FMT_PGP, key, &keylen, (gcry_mpi_t)privKey))
  {
	...
  }

But the call of gcry_mpi_print generates a segmentation fault. How can the=
=20
conversion be done?

Thanks in advance,
Ralf.
