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.
