无法从KeyStore获取密钥 [英] Can not get key from KeyStore

问题描述

我尝试从KeyStore获取Key。
我通过Keytool创建了一个密钥库：

I try to get Key from KeyStore. I created a keystore by Keytool:

keytool -genkeypair -dnamecn = Mark Jones，ou = JavaSoft，o = Sun，c = US - 别名business2 -keypass abcdtest -keystore C：\\\ workspace \XMLSample \ keystore \ mykeystore.jks -storepass 123456

keytool -genkeypair -dname "cn=Mark Jones, ou=JavaSoft, o=Sun, c=US" -alias business2 -keypass abcdtest -keystore C:\workspace\XMLSample\keystore\mykeystore.jks -storepass 123456

以下是GenerateXML.java

And the following is GenerateXML.java

import java.io.FileInputStream;
import java.security.KeyStore;
import java.security.cert.X509Certificate;
import javax.xml.crypto.dsig.XMLSignContext;
import javax.xml.crypto.dsig.XMLSignatureFactory;
import javax.xml.crypto.dsig.dom.DOMSignContext;
import javax.xml.parsers.DocumentBuilderFactory;
import org.w3c.dom.Document;

public class GenerateXML {

    public static void main(String[] args) throws Exception {

        try {
            char[] passwd = "123456".toCharArray();

            //Load the KeyStore and get the signing key and certificate
            KeyStore ks = KeyStore.getInstance("JKS");
            ks.load(new FileInputStream("C:\\workspace\\XMLSample\\keystore\\mykeystore.jks"), passwd);
            KeyStore.PrivateKeyEntry keyEnt = (KeyStore.PrivateKeyEntry)ks.getEntry("business2", new KeyStore.PasswordProtection(passwd));   // -> ERROR IN THIS ROW

            X509Certificate cert = (X509Certificate)keyEnt.getCertificate();

            //Create a DOMSignContext
            XMLSignContext context = new DOMSignContext(keyEnt.getPrivateKey(), doc.getDocumentElement()) ;

            //Create a DOM XMLSignatureFactory
            XMLSignatureFactory fac = XMLSignatureFactory.getInstance("DOM");

        } catch(Exception e) {
            e.printStackTrace();
            throw new Exception(e.toString());
        }
    }
}

我在Java 1.6上运行

I run on Java 1.6

但是有错误：

java.security.UnrecoverableKeyException: Cannot recover key
at sun.security.provider.KeyProtector.recover(KeyProtector.java:311)

推荐答案

这基本上意味着两件事，

This basically means 2 things,

1. 你的密码不好。


2. 您的密钥库以某种方式损坏。

我怀疑它是＃1。仔细检查您的密码。尝试使用相同的密码在keytool中列出密钥。

I suspect it's #1. Double check your password. Try if you can list the key in keytool with the same password.
