gnutls_x509_crt_get_issuer_dn - API function


#include <gnutls/x509.h> int gnutls_x509_crt_get_issuer_dn(gnutls_x509_crt_t cert, char * buf, size_t * buf_size);


gnutls_x509_crt_t cert should contain a gnutls_x509_crt_t type char * buf a pointer to a structure to hold the name (may be null) size_t * buf_size initially holds the size of buf


This function will copy the name of the Certificate issuer in the provided buffer. The name will be in the form "C=xxxx,O=yyyy,CN=zzzz" as described in RFC4514. The output string will be ASCII or UTF-8 encoded, depending on the certificate data. If buf is null then only the size will be filled. This function does not output a fully RFC4514 compliant string, if that is required see gnutls_x509_crt_get_issuer_dn3().


GNUTLS_E_SHORT_MEMORY_BUFFER if the provided buffer is not long enough, and in that case the buf_size will be updated with the required size. GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE if the DN does not exist, or another error value on error. On success 0 is returned.
