gnutls_x509_crt_set_spki(3)

gnutls_x509_crt_set_spki3

Api function

Usage

#include <gnutls/x509.h>

int gnutls_x509_crt_set_spki(gnutls_x509_crt_t crt, const gnutls_x509_spki_t spki, unsigned int flags);

Arguments

gnutls_x509_crt_t crt

a certificate of type gnutls_x509_crt_t

const gnutls_x509_spki_t spki

a SubjectPublicKeyInfo structure of type gnutls_x509_spki_t

unsigned int flags

must be zero

Overview

This function will set the certificate's subject public key information explicitly. This is intended to be used in the cases where a single public key (e.g., RSA) can be used for multiple signature algorithms (RSA PKCS1-1.5, and RSA-PSS).

To export the public key (i.e., the SubjectPublicKeyInfo part), check gnutls_pubkey_import_x509().

Returns

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