neon 0.34.2                                       15 April 2025                          NE_SSL_CERT_IDENTITY(3)

       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 commonname 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.

       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);
           }

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

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.
