NAME
       ne_ssl_cert_identity, ne_ssl_cert_signedby,
       ne_ssl_cert_issuer, ne_ssl_cert_subject - functions to
       access certificate properties

SYNOPSIS
       #include 

       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);
           }
