getDisplayNameFromCertificate

@Nullable
public static String getDisplayNameFromCertificate(@Nonnull
                                                             X509Certificate certificate,
                                                             boolean withLocation)
                                                      throws CertificateParsingException

Returns either a string that "sums up" the certificate for humans, in a similar manner to what you might see in a web browser, or null if one cannot be extracted. This will typically be the common name (CN) field, but can also be the org (O) field, org+location+country if withLocation is set, or the email address for S/MIME certificates.

Throws:

CertificateParsingException

                             throws KeyStoreException

Returns a key store loaded from the given stream. Just a convenience around the Java APIs.

Throws:
