Question

Did you spot the difference in the title? (for me, it took some time)

So I used bouncy castle with connection to java.security.cert.X509Certificate in order
to create certificates. Now I’m looking for a way to create a java.security.cert.X509Certificate from raw bytes. I haven’t any method to do this in
java.security.cert.X509Certificate but there is one(the getInstance static method) in
javax.security.cert.X509Certificate.

The problem is I cannot cast a javax.security.cert.X509Certificate to java.security.cert.X509Certificate.

Any ideas on what to do, to transform raw bytes into a java.security.cert.X509Certificate?

Also, what’s the differences between the one abstract class and the other class? Why does java has two of them with different functionality?

Answer 1

The javax version is deprecated. Use CertificateFactory to generate a certificate from raw bytes. There is an example in the javadocs.
