Pass NULL instead of an array of recipients to the encrypt function:

  If @var{recp} is @code{NULL}, symmetric rather than public key
  encryption is performed.  Symmetrically encrypted cipher text can be
  deciphered with @code{gpgme_op_decrypt}.  Note that in this case the
  crypto backend needs to retrieve a passphrase from the user.
  Symmetric encryption is currently only supported for the OpenPGP
  crypto backend.
