gnutls_certificate_get_issuer(3)

gnutls_certificate_get_issuer3

Api function

Usage

#include <gnutls/gnutls.h>

int gnutls_certificate_get_issuer(gnutls_certificate_credentials_t sc, gnutls_x509_crt_t cert, gnutls_x509_crt_t * issuer, unsigned int flags);

Arguments

gnutls_certificate_credentials_t sc

is a gnutls_certificate_credentials_t type.

gnutls_x509_crt_t cert

is the certificate to find issuer for

gnutls_x509_crt_t * issuer

Will hold the issuer if any. Should be treated as constant.

unsigned int flags

Use zero or GNUTLS_TL_GET_COPY

Overview

This function will return the issuer of a given certificate. If the flag GNUTLS_TL_GET_COPY is specified a copy of the issuer will be returned which must be freed using gnutls_x509_crt_deinit(). In that case the provided issuer must not be initialized.

As with gnutls_x509_trust_list_get_issuer() this function requires the GNUTLS_TL_GET_COPY flag in order to operate with PKCS11 trust lists in a thread-safe way.

Returns

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