        PEMParser pp = new PEMParser(new InputStreamReader(
                new FileInputStream("C:\\Certs\\mmdt.crt")));
        Object o = pp.readObject();
        X509CertificateHolder mmdtCert = (X509CertificateHolder) o;
        pp.close();
        System.out.println(mmdtCert.getSubjectPublicKeyInfo() + " Here");
    } catch (Exception e) {
        e.printStackTrace();
    }

but in android i get below error :

07-06 16:24:20.989: W/System.err(2949): java.lang.ClassCastException: org.bouncycastle.util.io.pem.PemObject

Answer 1

i found the answer but i do not delete this to use by others.

i could not find the reason of problem but i find a new solution.

CertificateFactory factory = CertificateFactory.getInstance("X.509");
X509Certificate x509Server;
ByteArrayInputStream bias = new ByteArrayInputStream(certBytes);
x509Server= (X509Certificate) factory.generateCertificate(bias);
