java - 无法将 X509 证书加载到 XML 数字签名中

Question

我正在使用 JDK 1.8.0_74。

我有基于标准做事方式(例如 http://www.oracle.com/technetwork/articles/javase/dig-signature-api-140772.html)创建 XML 数字签名的代码。

但是，我不想为签名 block 的 X509Data 元素加载 key 存储和 key ，我只想加载 X509Certificate 作为签名 block 的一部分，这会产生如下内容:

<ds:Signature xmlns:ds="http://www.w3.org/2000/09/xmldsig#">
<ds:SignedInfo>
<ds:CanonicalizationMethod Algorithm="http://www.w3.org/2001/10/xml-exc-c14n#"/>

<X509SerialNumber>5328</X509SerialNumber>
</X509IssuerSerial>
</ds:X509Data>
</ds:KeyInfo>
</ds:Signature>

(顺便说一句，这是我之前验证过的有效签名。)

现在，我的代码看起来像这样:

javax.xml.crypto.dsig.keyinfo.KeyInfoFactory kif = fac.getKeyInfoFactory();
        List x509Content = new ArrayList();

        X509Certificate certObj1 = null;

        try {
            InputStream fis = this.getClass().getClassLoader().getResourceAsStream("test.cert");
            certObj1 = (X509Certificate)(X509Certificate.getInstance(fis));
            fis.close();
            fis = null;                       
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (javax.security.cert.CertificateException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }        

        x509Content.add(certObj1);
        x509Content.add(certObj1.getSubjectDN().getName());

        javax.xml.crypto.dsig.keyinfo.X509Data xd = kif.newX509Data(x509Content);
        javax.xml.crypto.dsig.keyinfo.KeyInfo ki = kif.newKeyInfo(Collections.singletonList(xd));

但是，当这一行被执行时:

javax.xml.crypto.dsig.keyinfo.X509Data xd = kif.newX509Data(x509Content);

我得到一个异常(exception):

java.lang.ClassCastException: content[0] is not a valid X509Data type
    at org.jcp.xml.dsig.internal.dom.DOMX509Data.<init>(DOMX509Data.java:90)
    at org.jcp.xml.dsig.internal.dom.DOMKeyInfoFactory.newX509Data(DOMKeyInfoFactory.java:106)
    at com.abc.service.TestService.generateSignature(TestService.java:33...

查看了相应的代码(包括在线代码和反编译的实际 .class 文件)，它在 DOMX509Data 构造函数的这一部分失败了:

if (x509Type instanceof String) {
                new X500Principal((String)x509Type);
            } else if (!(x509Type instanceof byte[]) &&
                !(x509Type instanceof X509Certificate) &&
                !(x509Type instanceof X509CRL) &&
                !(x509Type instanceof XMLStructure)) {
                throw new ClassCastException
                    ("content["+i+"] is not a valid X509Data type");
            }

但是，如果我在自己的代码中复制/粘贴并重新创建相同的代码，则永远不会发生该异常!

对于我的生活，我无法弄清楚为什么会这样。我已经检查过 content[0] 的类型是 com.sun.security.cert.internal.x509.X509V1CertImpl ，它肯定扩展了 X509Certificate.

我做错了什么？我希望我忽略了某些事情，或者我正在做一些完全违法的事情。

如有任何帮助，我们将不胜感激。

提前致谢。

更新

虽然我仍然想知道这是为什么，但在感兴趣的时间里，我已经按照此处的示例 (http://www.oracle.com/technetwork/articles/javase/dig-signature-api-140772.html) 将其加载到证书主体中，但您首先必须将证书到 keystore (这可能有帮助:importing an existing x509 certificate and private key in Java keystore to use in ssl)。

此外，如果您只想加载序列信息而不是证书主体本身，请尝试这样的操作:

String dn = cert.getIssuerDN().toString();
BigInteger sn = cert.getSerialNumber();
X509IssuerSerial xd = kif.newX509IssuerSerial(dn, sn);

// next commented line was the original, replaced with the above line    
//javax.xml.crypto.dsig.keyinfo.X509Data xd = kif.newX509Data(x509Content);
javax.xml.crypto.dsig.keyinfo.KeyInfo ki = kif.newKeyInfo(Collections.singletonList(kif.newX509Data(Collections.singletonList(xd))));

Answer 1

我知道这有点晚了，但有一天可能会对某人有所帮助。

我遇到了同样的错误，在我的例子中，我传递了错误的别名。要查找别名，请在终端 (Windows) 上执行此命令:

keytool -v -list -keystore <jks file>

别名就在开头:

keytool -v -list -keystore keystore.jks

Enter keystore password:

Keystore type: JKS

Keystore type: JKS Keystore provider: SUN

Your keystore contains 1 entry

Alias name: (*bunch of numbers*) *alias name*
