NAME
gnutls_certificate_client_set_retrieve_function - Used to set a callback to retrieve the certificateSYNOPSIS
#include <gnutls/gnutls.h>void gnutls_certificate_client_set_retrieve_function(gnutls_certificate_credentials_t cred, gnutls_certificate_client_retrieve_function * func);
ARGUMENTS
- gnutls_certificate_credentials_t cred
- is a gnutls_certificate_credentials_t structure.
- gnutls_certificate_client_retrieve_function * func
- is the callback function
DESCRIPTION
This function sets a callback to be called in order to retrieve the certificate to be used in the handshake. The callback's function prototype is: int (*callback)(gnutls_session_t, const gnutls_datum_t* req_ca_dn, int nreqs, gnutls_pk_algorithm_t* pk_algos, int pk_algos_length, gnutls_retr_st* st);st should contain the certificates and private keys.
req_ca_cert, is only used in X.509 certificates. Contains a list with the CA names that the server considers trusted. Normally we should send a certificate that is signed by one of these CAs. These names are DER encoded. To get a more meaningful value use the function gnutls_x509_rdn_get().
pk_algos, contains a list with server's acceptable signature algorithms. The certificate returned should support the server's given algorithms.
If the callback function is provided then gnutls will call it, in the handshake, after the certificate request message has been received.
The callback function should set the certificate list to be sent, and return 0 on success. If no certificate was selected then the number of certificates should be set to zero. The value (-1) indicates error and the handshake will be terminated.
