Algorithm X509 not available

[Ashutosh Shinde]

I am trying to use a pfx file for client certification
The code is as below -
Security.addProvider(new org.bouncycastle.jce.provider.BouncyCastleProvider());
FileInputStream fis = new FileInputStream("D:\\CertificationServer\\merchantopus.pfx");
KeyStore ks2 = KeyStore.getInstance("PKCS12", "BC");
KeyManagerFactory kmf = kmf = KeyManagerFactory.getInstance("X509");
The following lines give the error -
java.security.NoSuchAlgorithmException: Algorithm X509 not available
at com.sun.net.ssl.b.a([DashoPro-V1.2-120198])
at com.sun.net.ssl.KeyManagerFactory.getInstance([DashoPro-V1.2-120198])
at BCTest.test(BCTest.java:28)
at BCTest.main(BCTest.java:12)
Could someone provide pointers to resolve the error?
Thanks,
Ashutosh

The error is actually quite meaningful - X509 isn't available as an algorithm. What this means is that none of the installed providers has an implementation of "X509" that can be used by KeyManagerFactory.
For instance, listing the available algorithms could be done like this :-

      StringBuffer sb = new StringBuffer();
      Provider[] p = Security.getProviders();
      for (int i = 0; i < p.length; i++) {
        sb.append("\nProvider : " + p[i].toString() + "\n");
        Set s = p[i].keySet();
        Object[] o = s.toArray();
        Arrays.sort(o);
        for (int j = 1; j < o.length; j++) {
          sb.append(o[j].toString() + ", ");
        }
      }
      System.out.println(sb.toString());

You will probably find that X509 is not listed.
I'm haven't used the bouncy castle provider, however, there should be a algorightm that is supplied with the JDK (at least it was with jdk1.3) called SunX509 which can be used when invoking KeyManagerFactory.getInstance()
