gnutls_x509_crt_set_issuer_dn_by_oid - Set the Certificate request issuer’s distinguished name


#include <gnutls/x509.h>

int gnutls_x509_crt_set_issuer_dn_by_oid(gnutls_x509_crt_t crt, const char * oid, unsigned int raw_flag, const void * name, unsigned int sizeof_name);


gnutls_x509_crt_t crt should contain a gnutls_x509_crt_t structure
const char * oid holds an Object Identifier in a null terminated string
unsigned int raw_flag must be 0, or 1 if the data are DER encoded
const void * name a pointer to the name
unsigned int sizeof_name holds the size of name


This function will set the part of the name of the Certificate issuer, specified by the given OID. The input string should be ASCII or UTF-8 encoded.

Some helper macros with popular OIDs can be found in gnutls/x509.h With this function you can only set the known OIDs. You can test for known OIDs using gnutls_x509_dn_oid_known(). For OIDs that are not known (by gnutls) you should properly DER encode your data, and call this function with raw_flag set.

Normally you do not need to call this function, since the signing operation will copy the signer’s name as the issuer of the certificate.


On success, GNUTLS_E_SUCCESS is returned, otherwise a negative error value.
