[英]How to sign an saml 2.0 assertion using the openssl (.PCKS8) file
Hi i need some infomation on saml 2.0 Authn Request . 嗨我需要关于saml 2.0 Authn请求的一些信息。 I want to sign my authn request with a openssl created *.pkcs8 file.
我想用openssl创建的* .pkcs8文件签署我的authn请求。 I can do with a keystore file using java keytool .
我可以使用java keytool来处理密钥库文件。 But I want to achieve the same using *.PKCS8 file generateing using the openssl.
但是我希望使用openssl生成使用* .PKCS8文件来实现相同的功能。 I have been struggling with this for some time .
我一直在努力解决这个问题。 I am able to generate the xml with it .
我能用它生成xml。

Also tell me is my Authn Request complete . 还告诉我是我的Authn请求完成。 Also is the Authn request same for both the Artifact and POST(Assertion) saml message
对于Artifact和POST(断言)saml消息,Authn请求也是相同的
PLS HELP !!! PLS帮助!!!
How are you constructing your org.opensaml.xml.security.credential.Credential
object ? 你是如何构建
org.opensaml.xml.security.credential.Credential
对象的? You can only load a private-key from PKCS8 file. 您只能从PKCS8文件加载私钥 。 You still need the public-key to fully construct the Credential object.
您仍然需要公钥来完全构造Credential对象。 If your public-key is stored in DER encoded bytes you can use the following code to create the
Credential
and use that to sign the request 如果您的公钥存储在DER编码的字节中,您可以使用以下代码创建
Credential
并使用它来签署请求
/**
* 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);
}
You can use this to output the keyinfo 您可以使用它来输出keyinfo
X509KeyInfoGeneratorFactory fact = new X509KeyInfoGeneratorFactory();
fact.setEmitEntityCertificate(true);
signature.setKeyInfo(fact.newInstance().generate(cred));
