    有时需要获取windows系统安装的证书或证书链，比如说你要通过证书来创建java的密钥库  。

有关证书链的解释可以查看此处 。

 

public static void main(String[] args) {SunMSCAPI providerMSCAPI = new SunMSCAPI();Security.addProvider(providerMSCAPI);KeyStore ks;SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");try {ks = KeyStore.getInstance("Windows-MY");ks.load(null, null);      Enumeration aliases = ks.aliases();              while (aliases.hasMoreElements()) {                  String alias = (String)aliases.nextElement();                            Certificate[] certs = ks.getCertificateChain(alias);                  if (certs != null) {                      System.out.println("证书链：" + alias + "':");                      for (int c = 0; c < certs.length; c++) {                          if (certs[c] instanceof X509Certificate) {                              X509Certificate cert = (X509Certificate)certs[c];                              System.out.println("  顺序: " + (c + 1) + ":");                              System.out.println("  主题: " + cert.getSubjectDN());                              System.out.println("  签名算法: " + cert.getSigAlgName());                              System.out.println("  签发时间: " + sdf.format(cert.getNotBefore()) );                              System.out.println("  到期时间: " +sdf.format(cert.getNotAfter()));                              System.out.println("  签发者: " + cert.getIssuerDN());                          }                      }                  }              }} catch (Exception e) {e.printStackTrace();}}
