Name

gnutls_x509_crt_get_extension_data — Get the specified extension data

Synopsis

#include <gnutls/x509.h>
int gnutls_x509_crt_get_extension_data( gnutls_x509_crt_t   cert,
  int   indx,
  void *   data,
  size_t *   sizeof_data);

ARGUMENTS

gnutls_x509_crt_t cert

should contain a gnutls_x509_crt_t structure

int indx

Specifies which extension OID to send. Use zero to get the first one.

void * data

a pointer to a structure to hold the data (may be null)

size_t * sizeof_data

initially holds the size of oid

DESCRIPTION

This function will return the requested extension data in the certificate. The extension data will be stored as a string in the provided buffer.

Use gnutls_x509_crt_get_extension_info() to extract the OID and critical flag. Use gnutls_x509_crt_get_extension_by_oid() instead, if you want to get data indexed by the extension OID rather than sequence.

Return 0 on success. A negative value may be returned in case of parsing error. If you have reached the last extension available GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned.

REPORTING BUGS

Report bugs to <bug-gnutls@gnu.org>.
