java - keystore 的 setkeyentity 的参数

Question

我使用 keystore 来保护文件中的私钥，使用以下代码

ks.setKeyEntry("kk1", pr, pass, cert1);//ks is obj of keystore,
                                       //kk1 is alias,
                                       //pr-->is private key,
                                       //pass->is the password to protect that key,
                                       //cert1-->is the certificate chain..

后来我想将它存储在文件中，使用存储功能。我的问题是

  (actual argument java.security.cert.X509Certificate cannot be converted to java.security.cert.Certificate[] by method invocation conversion)

我已将 cert1 指定为

 X509V3Create obj=new   X509V3Create();  //it is my own class
 X509Certificate cert1  = obj.generateV3Certificate(pair);
 //in this method I set all the certificate parameters like version,alg etc..,pair is obj of key pair...

我收到上面提到的错误..我无法将该参数设置为 null(它给出空指针异常)

我应该传递什么作为参数？？？

试试这个:

java.security.cert.Certificate[] certificateChain = new java.security.cert.Certificate[]{cert1}
ks.setKeyEntry("kk1", pr, pass, certificateChain);
