**#include \<gnutls/openpgp.h\>**

**int gnutls\_certificate\_get\_openpgp\_crt(gnutls\_certificate\_credentials\_t** *res***, unsigned** *index***, gnutls\_openpgp\_crt\_t \*\*** *crt\_list***, unsigned \*** *crt\_list\_size***);**

## ARGUMENTS

- gnutls\_certificate\_credentials\_t res

  is a **gnutls\_certificate\_credentials\_t** type.

- unsigned index

## DESCRIPTION

Obtains a X.509 certificate list that has been stored in  *res* with one of **gnutls\_certificate\_set\_openpgp\_key()**, **gnutls\_certificate\_set\_openpgp\_key\_file()**, **gnutls\_certificate\_set\_openpgp\_key\_file2()**, **gnutls\_certificate\_set\_openpgp\_key\_mem()**, or **gnutls\_certificate\_set\_openpgp\_key\_mem2()**.  Each certificate in the returned certificate list must be deallocated with **gnutls\_openpgp\_crt\_deinit()**, and the list itself must be freed with **gnutls\_free()**.

If there is no certificate with the given index, **GNUTLS\_E\_REQUESTED\_DATA\_NOT\_AVAILABLE** is returned. If the certificate with the given index is not a X.509 certificate, **GNUTLS\_E\_INVALID\_REQUEST** is returned.
