gnutls_x509_crt_set_version - Man Page

API function


#include <gnutls/x509.h>

int gnutls_x509_crt_set_version(gnutls_x509_crt_t crt, unsigned int version);


gnutls_x509_crt_t crt

a certificate of type gnutls_x509_crt_t

unsigned int version

holds the version number. For X.509v1 certificates must be 1.


This function will set the version of the certificate.  This must be one for X.509 version 1, and so on.  Plain certificates without extensions must have version set to one.

To create well-formed certificates, you must specify version 3 if you use any certificate extensions.  Extensions are created by functions such as gnutls_x509_crt_set_subject_alt_name() or gnutls_x509_crt_set_key_usage().


On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error value.
