# [NAME](#NAME)

gnutls\_x509\_crt\_set\_dn\_by\_oid - API function

# [SYNOPSIS](#SYNOPSIS)

**#include <gnutls/x509.h>**

**int gnutls\_x509\_crt\_set\_dn\_by\_oid(gnutls\_x509\_crt\_t crt, const char * oid, unsigned int raw\_flag, const void * name, unsigned int sizeof\_name);**

# [ARGUMENTS](#ARGUMENTS)

[gnutls\_x509\_crt\_t crt](#gnutls_x509_crt_t)

a certificate of type **gnutls\_x509\_crt\_t**

[const char * oid](#const)

holds an Object Identifier in a null terminated string

[unsigned int raw\_flag](#unsigned)

must be 0, or 1 if the data are DER encoded

[const void * name](#const~2)

a pointer to the name

[unsigned int sizeof\_name](#unsigned~2)

holds the size of *name*

# [DESCRIPTION](#DESCRIPTION)

This function will set the part of the name of the Certificate subject, 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.

# [RETURNS](#RETURNS)

On success, **GNUTLS\_E\_SUCCESS** (0) is returned, otherwise a negative error value.
