Generate X509Certificate from byte[]?

Question

Is there a possibility to generate an java.security.cert.X509Certificate from an byte[]?

Answer 1

You can do something like:

X509Certificate certificate = signature.getKeyInfo().getX509Datas().get(0).getX509Certificates().get(0);

String lexicalXSDBase64Binary = certificate.getValue();
byte[] decoded = DatatypeConverter.parseBase64Binary(lexicalXSDBase64Binary);


CertificateFactory certFactory = CertificateFactory.getInstance("X.509");
Certificate cert = certFactory.generateCertificate(new ByteArrayInputStream(decoded));
