Here is a sample code for reading a certificate file (which is stored in
X509 format).

<code>

 FileInputStream is = new FileInputStream("testCertificate.crt") ;
 CertificateFactory lFactory = CertificateFactory.getInstance("X.509") ;
 Certificate cert = lFactory.generateCertificate(is) ;

</code>
