Converting PEM cert to X509Certificate object in Java

 In firefox, when we select the certificate of the website and click on view certificate, it gives us the option to download PEM cert or PEM cert chain. For my use case, I need to work with java.security.cert.X509Certificate. The code to do this is:

 

InputStream is = ...//read the PEM cert file
java.security.cert.CertificateFactory cf = java.security.cert.CertificateFactory.getInstance("X.509");
java.security.cert.X509Certificate cert = (java.security.cert.X509Certificate)cf.generateCertificate(is);
