我正在尝试使用Java中的签名(俄语GOST34.10-2001算法)为某些政府服务创建SOAP消息。问题是该服务告诉我Signature无效,我无法看到我在哪里犯了错误。我从中读取私钥和证书的密钥容器是有效的。 哪里出错了?我知道我的问题非常具体,但我仍然希望有人能指引我。
update1:一点点更新:消息正文有一些西里尔(utf)-8节点和值 UPDATE2: 所以我通读了this question并尝试以相同的方式获取PrivateKey并获得此异常: java.lang.IllegalArgumentException:私钥算法与最终实体证书中的公钥算法不匹配
以下是一些代码:
这里我将类编组到SOAP正文中:
try {
MessageFactory mf = MessageFactory.newInstance();
SOAPMessage sm = mf.createMessage();
SOAPPart sp = sm.getSOAPPart();
SOAPEnvelope envelope = sp.getEnvelope();
QName bodyId = new QName("http://ws.unisoft/", "SendFullULRequest");
SOAPBody sb = (SOAPBody) envelope.getBody();
SOAPHeader sh = (SOAPHeader) envelope.getHeader();
javax.xml.bind.JAXBContext jaxbCtx = javax.xml.bind.JAXBContext.newInstance(FullULRq.class);
javax.xml.bind.Marshaller marshaller = jaxbCtx.createMarshaller();
marshaller.marshal(new JAXBElement<FullULRq>(bodyId, FullULRq.class, fulr),
sm.getSOAPBody());
sm.saveChanges();
然后我计算摘要值:
ReferenceType rt2 = new ReferenceType();
rt2.setURI("#body");

ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
Source xmlSource = new DOMSource(sm.getSOAPBody());
Result outputTarget = new StreamResult(outputStream);
try {
Transformer transformer = TransformerFactory.newInstance().newTransformer();
transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
transformer.setOutputProperty(OutputKeys.INDENT, "no");
transformer.transform(xmlSource, outputTarget);
Init.init();
Canonicalizer canon = Canonicalizer.getInstance(Canonicalizer.ALGO_ID_C14N_EXCL_OMIT_COMMENTS);
final ByteArrayInputStream is = new ByteArrayInputStream(canon.canonicalize(outputStream.toByteArray()));
rt2.setDigestValue(computeDigestWithStream(is));
} catch (Exception e) {
e.printStackTrace();
}
使用这种方法:
public static byte[] computeDigestWithStream(ByteArrayInputStream stream) throws Exception {
final MessageDigest digest =
MessageDigest.getInstance("GOST3411");
// processing data
final DigestInputStream digestStream =
new DigestInputStream(stream, digest);
while (digestStream.available() != 0) {
digestStream.read();
}
最后我从块中生成一个签名(其中存在元素):
ByteArrayOutputStream outputStream2 = new ByteArrayOutputStream();
Source xmlSource2 = new DOMSource(sm.getSOAPBody());
Result outputTarget2 = new StreamResult(outputStream2);
Transformer transformer = TransformerFactory.newInstance().newTransformer();
transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
transformer.setOutputProperty(OutputKeys.INDENT, "no");
transformer.transform(xmlSource2, outputTarget2);
Init.init();
Canonicalizer canon = Canonicalizer.getInstance(Canonicalizer.ALGO_ID_C14N_EXCL_OMIT_COMMENTS);
InputStream is2 = new ByteArrayInputStream(outputStream2.toByteArray());
byte[] bb = canon.canonicalize(outputStream2.toByteArray());
byte[] signval = sign("CryptoProSignature", key, bb);
sign()方法:
public static byte[] sign(String algorithmName, PrivateKey privateKey, byte[] data) throws Exception {
final Signature sig = Signature.getInstance(algorithmName);
sig.initSign(privateKey);
sig.update(data);
return sig.sign();
}
如果它是相关的,这就是我从容器中读取privateKey的方式:
KeyStore ks = KeyStore.getInstance("FloppyStore");
String passwd = "*";
String kalias = null;
ks.load(null, null);
Enumeration enum1 = ks.aliases();
for (; enum1.hasMoreElements();) {
String tAlias = (String) enum1.nextElement();
if (ks.isKeyEntry(tAlias)) {
kalias = tAlias;
}
System.out.println(tAlias);
}
PrivateKey key = (PrivateKey) ks.getKey(kalias, passwd.toCharArray());
谢谢!
