gnutls_certificate_get_issuer(3)

NAME
gnutls_certificate_get_issuer - API function

SYNOPSIS
#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

DESCRIPTION
This function will return the issuer of a given certificate. As with gnutls_x509_trust_list_get_issuer() this function requires the GNUTLS_TL_GET_COPY flag in order to operate with PKCS 11 trust lists. In that case the issuer must be freed using gnutls_x509_crt_deinit().

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

SINCE
3.0
