NAME
ne_ssl_cert_identity, ne_ssl_cert_signedby, ne_ssl_cert_issuer,
ne_ssl_cert_subject - functions to access certificate properties
SYNOPSIS
#include <ne_ssl.h>
const char *ne_ssl_cert_identity(const ne_ssl_certificate *cert);
const ne_ssl_certificate
*ne_ssl_cert_signedby(const ne_ssl_certificate *cert);
const ne_ssl_dname
*ne_ssl_cert_subject(const ne_ssl_certificate *cert);
const ne_ssl_dname *ne_ssl_cert_issuer(const ne_ssl_certificate *cert);
DESCRIPTION
The function ne_ssl_cert_identity retrieves the "identity" of a
certificate; for an SSL server certificate, this will be the hostname
for which the certificate was issued. In PKI parlance, the identity is
the common name attribute of the distinguished name of the certificate
subject.
The functions ne_ssl_cert_subject and ne_ssl_cert_issuer can be used to
access the objects representing the distinguished name of the subject
and of the issuer of a certificate, respectively.
If a certificate object is part of a certificate chain, then
ne_ssl_cert_signedby can be used to find the certificate which signed a
particular certificate. For a self-signed certificate or a certificate
for which the full chain is not available, this function will return
NULL.
RETURN VALUE
ne_ssl_cert_issuer and ne_ssl_cert_subject are guaranteed to never
return NULL. ne_ssl_cert_identity may return NULL if the certificate
has no specific "identity". ne_ssl_cert_signedby may return NULL as
covered above.
EXAMPLES
The following function could be used to display information about a
given certificate:
void dump_cert(const ne_ssl_certificate *cert) {
const char *id = ne_ssl_cert_identity(cert);
char *dn;
if (id)
printf("Certificate was issued for '%s'.\n", id);
dn = ne_ssl_readable_dname(ne_ssl_cert_subject(cert));
printf("Subject: %s\n", dn);
free(dn);
dn = ne_ssl_readable_dname(ne_ssl_cert_issuer(cert));
printf("Issuer: %s\n", dn);
free(dn);
}
