關於如何登錄EPES

Question

的小費小費在這一刻，我在簽名EPES上工作，我想要一些信息;

籤，我在SignerTestBase.java：

public class SignerTestBase extends SignatureServicesTestBase 

{

static protected KeyingDataProvider keyingProviderMy; 
static protected KeyingDataProvider keyingProviderNist; 

static 
{ 
    try 
    { 
     keyingProviderMy = createFileSystemKeyingDataProvider("pkcs12", "my/LG.pfx", "mykeypass", true); 
     keyingProviderNist = createFileSystemKeyingDataProvider("pkcs12", "csrc.nist/test4.p12", "password", false); 
    } catch (KeyStoreException e) 
    { 
     throw new NullPointerException("SignerTestBase init failed: " + e.getMessage()); 
    } 
} 
public static Document getTestDocument() throws Exception 
    { 
     //return getDocument("document.xml"); 

     //==that I changed===================================================================== 
     **return getDocument("b.xml");** 


} 

和：

@Test 
public void testSignEPES() throws Exception 
{ 
    System.out.println("signEPES"); 

    Document doc = getTestDocument(); 

    Element elemToSign = doc.getDocumentElement(); 

    SignerEPES signer = (SignerEPES)new XadesEpesSigningProfile(keyingProviderMy, policyInfoProvider).newSigner(); 
    new Enveloped(signer).sign(elemToSign); 

    **outputDocument(doc, "document.signed.epes.xml");** 
} 

在主：

System.out.println("============================================================================");   
     System.out.println("XADESTEST : EPES SIGNATURE"); 
     System.out.println("============================================================================"); 
     System.out.println(); 

     SignerEPESTest signerEPESTest = new SignerEPESTest(); 
     System.out.println("signerEPESTest : " + signerEPESTest.toString()); 


     /** 
     * ==== NOT OK ===== 
     */ 

     **signerEPESTest.testSignEPES();** 

，在我的控制檯，當我運行：

============================================================================ 
XADESTEST : EPES SIGNATURE 
============================================================================ 

signerEPESTest : xadestest.SignerEPESTest@1c63e8c 
signEPES

    at xadestest.XadesTest.main(XadesTest.java:103)

請在我尋找，任何人可以幫助我嗎？

Answer 1

似乎對XadesEpesSigningProfile的policyInfoProvider參數爲null。構造函數缺少一個更好的消息空檢查。
