gnutls_certificate_set_key — API function


#include <gnutls/abstract.h>

int gnutls_certificate_set_key(gnutls_certificate_credentials_t res, const char ** names, int names_size, gnutls_pcert_st * pcert_list, int pcert_list_size, gnutls_privkey_t key);


gnutls_certificate_credentials_t res

is a gnutls_certificate_credentials_t type.

const char ** names

is an array of DNS name of the certificate (NULL if none)

int names_size

holds the size of the names list

gnutls_pcert_st * pcert_list

contains a certificate list (path) for the specified private key

int pcert_list_size

holds the size of the certificate list

gnutls_privkey_t key

is a gnutls_privkey_t key


This function sets a certificate/private key pair in the gnutls_certificate_credentials_t type.  This function may be called more than once, in case multiple keys/certificates exist for the server.  For clients that want to send more than their own end- entity certificate (e.g., also an intermediate CA cert), the full certificate chain must be provided in  pcert_list .

Note that the  key and the elements of  pcert_list will become part of the credentials structure and must not be deallocated. They will be automatically deallocated when the  res structure is deinitialized.

If that function fails to load the  res structure is at an undefined state, it must not be reused to load other keys or certificates.

Note that, this function by default returns zero on success and a negative value on error. Since 3.5.6, when the flag GNUTLS_CERTIFICATE_API_V2 is set using gnutls_certificate_set_flags() it returns an index (greater or equal to zero). That index can be used to other functions to refer to the added key-pair.


On success this functions returns zero, and otherwise a negative value on error (see above for modifying that behavior).
