Convert X509Certificate into .p7b file

843811Jan 30 2007 — edited Oct 26 2008

I have a X509Certificate and I'd like to save it into a PKCS#7 .p7b file. Currently, I'm able to save it into a .cer file with the following code:

 private void writeCertificate(Writer writer,
                                X509Certificate cert)
    throws Exception
    {
    writer.write(BEGIN_CERTIFICATE_MARKER);
    writer.write("\n");
    writer.write(new String(Base64.encode(cert.getEncoded())));
    writer.write("\n");
    writer.write(END_CERTIFICATE_MARKER);
    writer.close();
    }

What do I need to do to save as a .p7b file instead?
