# [NAME](#NAME)

gnutls\_certificate\_get\_crt\_raw - API function

# [SYNOPSIS](#SYNOPSIS)

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

**int gnutls\_certificate\_get\_crt\_raw(gnutls\_certificate\_credentials\_t sc, unsigned idx1, unsigned idx2, gnutls\_datum\_t * cert);**

# [ARGUMENTS](#ARGUMENTS)

[gnutls\_certificate\_credentials\_t sc](#gnutls_certificate_credentials_t)

is a **gnutls\_certificate\_credentials\_t** type.

[unsigned idx1](#unsigned)

the index of the certificate chain if multiple are present

[unsigned idx2](#unsigned~2)

the index of the certificate in the chain. Zero gives the server's certificate.

[gnutls\_datum\_t * cert](#gnutls_datum_t)

Will hold the DER encoded certificate.

# [DESCRIPTION](#DESCRIPTION)

This function will return the DER encoded certificate of the server or any other certificate on its certificate chain (based on *idx2* ). The returned data should be treated as constant and only accessible during the lifetime of *sc* . The *idx1* matches the value **gnutls\_certificate\_set\_x509\_key()** and friends functions.

# [RETURNS](#RETURNS)

On success, **GNUTLS\_E\_SUCCESS** (0) is returned, otherwise a negative error value. In case the indexes are out of bounds **GNUTLS\_E\_REQUESTED\_DATA\_NOT\_AVAILABLE** is returned.
