-----END CERTIFICATE-----代码：（摘自jdk1.5.chm)
InputStream inStream = new FileInputStream("D:\\abase64.cer");
CertificateFactory cf = CertificateFactory.getInstance("X.509");
X509Certificate cert = (X509Certificate)cf.generateCertificate(inStream);
inStream.close();
String dn = cert.getSubjectX500Principal().getName(); Eclipse显示：CN=*a,OU=N*TP*,O=*X*P*a*s*s,C=CN
C++,C#,windows显示：C=CN, O=XPass, OU=产品部, CN=a这是为什么？windows的显示是正确的，谁能提供个合适的？由于需要跨平台(windows,linux等)
