Right now i am encrypting and decrypting information using RSA algorithm and generating public and private key from

you can make use of this command below . this requires itext.jar
CertificateFactory cf = CertificateFactory.getInstance("X509"); Collection col = cf.generateCertificates(new FileInputStream("export.cer"));
I agree. Here's the link:
