Java 如何使用openssl（.PCKS8）文件对SAML2.0断言进行签名

嗨，我需要一些关于SAML2.0身份验证请求的信息。我想用openssl创建的*.pkcs8文件签署我的authn请求。我可以使用JavaKeyTool处理密钥库文件。但我希望通过使用openssl生成*.PKCS8文件来实现同样的效果。我已经为此挣扎了一段时间。我能够用它生成xml

同时告诉我我的授权请求是否完成。 工件和POST（断言）saml消息的Authn请求是否相同

请帮忙

您可以使用它来输出keyinfo

X509KeyInfoGeneratorFactory fact = new X509KeyInfoGeneratorFactory();
fact.setEmitEntityCertificate(true);
signature.setKeyInfo(fact.newInstance().generate(cred));

如何构造

org.opensaml.xml.security.credential.credential

对象？ 您只能从PKCS8文件加载。您仍然需要公钥来完全构造凭证对象。如果您的公钥存储在编码字节中，您可以使用以下代码创建

凭证

，并使用该代码对请求进行签名

/**
 * Load privateKeyDerBytes from PKCS8 file and publicKeyDerBytes from .cer, .crt, .der files
 */
private static Credential getCredential(byte[] privateKeyDerBytes , byte[] publicKeyDerBytes) throws IOException
{
    PrivateKey privateKey = PKCS8Key.parse(new DerValue( privateKeyDerBytes ));
    PublicKey publicKey = X509Key.parse(new DerValue(publicKeyDerBytes));
    BasicCredential basicCredential = new BasicCredential();
    basicCredential.setUsageType(UsageType.SIGNING);
    basicCredential.setPrivateKey(privateKey);
    basicCredential.setPublicKey(publicKey);
    return basicCredential;
}

public static void signAssertion(Assertion assertion , byte[] privateKeyDerBytes , byte[] publicKeyDerBytes) throws IOException, SecurityException
{
    // get Credential 
    Credential credential = getCredential(privateKeyDerBytes, publicKeyDerBytes);
    // create Signature
    Signature signature = (Signature) Configuration.getBuilderFactory().getBuilder(
            Signature.DEFAULT_ELEMENT_NAME).buildObject(
            Signature.DEFAULT_ELEMENT_NAME);

    signature.setSigningCredential(credential);
    signature
            .setSignatureAlgorithm(SignatureConstants.ALGO_ID_SIGNATURE_RSA_SHA1);
    signature
            .setCanonicalizationAlgorithm(SignatureConstants.ALGO_ID_C14N_EXCL_OMIT_COMMENTS);
    signature.setKeyInfo(getKeyInfo(credential));

    assertion.setSignature(signature);

}

public static KeyInfo getKeyInfo(Credential credential)
        throws SecurityException {
    SecurityConfiguration secConfiguration = Configuration
            .getGlobalSecurityConfiguration();
    NamedKeyInfoGeneratorManager namedKeyInfoGeneratorManager = secConfiguration
            .getKeyInfoGeneratorManager();
    KeyInfoGeneratorManager keyInfoGeneratorManager = namedKeyInfoGeneratorManager
            .getDefaultManager();
    KeyInfoGeneratorFactory factory = keyInfoGeneratorManager
            .getFactory(credential);
    KeyInfoGenerator generator = factory.newInstance();
    return generator.generate(credential);

}

只是为了证实我是这样做的。”Signature Signature=（Signature）Configuration.getBuilderFactory（）.getBuilder（Signature.DEFAULT\u ELEMENT\u NAME）.buildObject（Signature.DEFAULT\u ELEMENT\u NAME）；X509KeyInfoGeneratorFactory事实=新的X509KeyInfoGeneratorFactory（）；事实。setEmitEntityCertificate（真）；请尝试{signature.setKeyInfo（fact.newInstance（）.generate（signingCredential））；}catch（SecurityException e）{//TODO自动生成的catch块e.printStackTrace（）；}samlMessage.setSignature（signature）；'你以前就是这么做的吗？不是。我只是把你的代码，并试图以这种方式添加它。但它没有生成所需的keyInfo（使用x506cert）。实际上需要将Keyinfo设置为凭证。这是否可能，一旦我获得签名凭证，我就不确定了。这是我编码和发送authn请求的代码。HttpServletResponsedAdapter outTransport=new HttpServletResponsedAdapter（response，false）；BasicSAMLMessageContext=新的BasicSAMLMessageContext（）；messageContext.setOutboundMessageTransport（outTransport）；messageContext.setPeerEntityEndpoint（端点）；messageContext.setOutboundSAMLMessage（samlMessage）；messageContext.setOutboundMessageIssuer（issuingEntityName）；messageContext.setRelayState（clientId）；messageContext.setOutboundSAMLMessageSigningCredential（signingCredential）；encoder.encode（messageContext）；谢谢你，纳迪尔萨加尔。我会核实你的建议，然后再给你回复。
