Getting the Subject and Issuer Distinguished Names of an X509 Certificate
This example lists the subject and issuer distinguished names of the
certificates in a keystore. To load a keystore, see
Listing the Aliases in a Key Store.
try {
// List the aliases
Enumeration enum = keystore.aliases();
for (; enum.hasMoreElements(); ) {
String alias = (String)enum.nextElement();
java.security.cert.Certificate cert = keystore.getCertificate(alias);
if (cert instanceof X509Certificate) {
X509Certificate x509cert = (X509Certificate)cert;
// Get subject
Principal principal = x509cert.getSubjectDN();
String subjectDn = principal.getName();
// Get issuer
principal = x509cert.getIssuerDN();
String issuerDn = principal.getName();
}
}
} catch (KeyStoreException e) {
}
