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);
}
