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);
a certificate of type gnutls_x509_crt_t
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
On success, GNUTLS_E_SUCCESS is returned, otherwise a
negative error value.
