x509 certificate parsing libraries for Java

Question

Any recommended crypto libraries for Java. What I need is the ability to parse X.509 Certificates to extract the information contained in them.

Thanks

Answer 1

There's a lot more in most certificates than what's handled by java.security.cert.X509Certificate. If you need to parse extension values, check out the Bouncy Castle Crypto API. (C# version is offered too.)

Answer 2

In Java, java.security.cert.CertificateFactory.

"A certificate factory for X.509 must return certificates that are an instance of java.security.cert.X509Certificate"
