Chapter 374. XML Security Component

Available as of Camel version 2.12

With this Apache Camel component, you can generate and validate XML signatures as described in the W3C standard XML Signature Syntax and Processing or as described in the successor version 1.1. For XML Encryption support, please refer to the XML Security Data Format.

You can find an introduction to XML signature here. The implementation of the component is based on JSR 105, the Java API corresponding to the W3C standard and supports the Apache Santuario and the JDK provider for JSR 105. The implementation will first try to use the Apache Santuario provider; if it does not find the Santuario provider, it will use the JDK provider. Further, the implementation is DOM based.

Since Camel 2.15.0 we also provide support for XAdES-BES/EPES for the signer endpoint; see subsection "XAdES-BES/EPES for the Signer Endpoint".

Maven users will need to add the following dependency to their pom.xml for this component: 

<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-xmlsecurity</artifactId>
    <version>x.x.x</version>
    <!-- use the same version as your Camel core version -->
</dependency>

374.1. XML Signature Wrapping Modes

XML Signature differs between enveloped, enveloping, and detached XML signature. In the enveloped XML signature case, the XML Signature is wrapped by the signed XML Document; which means that the XML signature element is a child element of a parent element, which belongs to the signed XML Document. In the enveloping XML signature case, the XML Signature contains the signed content. All other cases are called detached XML signatures. A certain form of detached XML signature is supported since 2.14.0.

In the enveloped XML signature case, the supported generated XML signature has the following structure (Variables are surrounded by []). 

<[parent element]>
   ... <!-- Signature element is added as last child of the parent element-->
   <Signature Id="generated_unique_signature_id">
       <SignedInfo>
             <Reference URI="">
                   <Transform Algorithm="http://www.w3.org/2000/09/xmldsig#enveloped-signature"/>
                   (<Transform>)* <!-- By default "http://www.w3.org/2006/12/xml-c14n11" is added to the transforms -->
                   <DigestMethod>
                   <DigestValue>
             </Reference>
             (<Reference URI="#[keyinfo_Id]">
                   <Transform Algorithm="http://www.w3.org/TR/2001/REC-xml-c14n-20010315"/>
                   <DigestMethod>
                   <DigestValue>
             </Reference>)?
             <!-- further references possible, see option 'properties' below -->
      </SignedInfo>
      <SignatureValue>
      (<KeyInfo Id="[keyinfo_id]">)?
      <!-- Object elements possible, see option 'properties' below -->
  </Signature>
</[parent element]>

In the enveloping XML signature case, the supported generated XML signature has the structure: 

<Signature Id="generated_unique_signature_id">
  <SignedInfo>
         <Reference URI="#generated_unique_object_id" type="[optional_type_value]">
               (<Transform>)* <!-- By default "http://www.w3.org/2006/12/xml-c14n11" is added to the transforms -->
               <DigestMethod>
               <DigestValue>
         </Reference>
         (<Reference URI="#[keyinfo_id]">
               <Transform Algorithm="http://www.w3.org/TR/2001/REC-xml-c14n-20010315"/>
               <DigestMethod>
               <DigestValue>
         </Reference>)?
          <!-- further references possible, see option 'properties' below  -->
  </SignedInfo>
  <SignatureValue>
  (<KeyInfo Id="[keyinfo_id]">)?
  <Object Id="generated_unique_object_id"/> <!-- The Object element contains the in-message body; the object ID can either be generated or set by the option parameter "contentObjectId" -->
  <!-- Further Object elements possible, see option 'properties' below -->
</Signature>

As of 2.14.0 detached XML signatures with the following structure are supported (see also sub-chapter XML Signatures as Siblings of Signed Elements): 

(<[signed element] Id="[id_value]">
<!-- signed element must have an attribute of type ID -->
      ...

</[signed element]>
<other sibling/>*
<!-- between the signed element and the corresponding signature element, there can be other siblings.
 Signature element is added as last sibling. -->
<Signature Id="generated_unique_ID">
   <SignedInfo>
      <CanonicalizationMethod>
      <SignatureMethod>
      <Reference URI="#[id_value]" type="[optional_type_value]">
      <!-- reference URI contains the ID attribute value of the signed element -->
            (<Transform>)* <!-- By default "http://www.w3.org/2006/12/xml-c14n11" is added to the transforms -->
            <DigestMethod>
            <DigestValue>
      </Reference>
      (<Reference URI="#[generated_keyinfo_Id]">
            <Transform Algorithm="http://www.w3.org/TR/2001/REC-xml-c14n-20010315"/>
            <DigestMethod>
            <DigestValue>
      </Reference>)?
   </SignedInfo>
   <SignatureValue>
   (<KeyInfo Id="[generated_keyinfo_id]">)?
</Signature>)+

374.2. URI Format

The camel component consists of two endpoints which have the following URI format: 

xmlsecurity:sign:name[?options]
xmlsecurity:verify:name[?options]
  • With the signer endpoint, you can generate a XML signature for the body of the in-message which can be either a XML document or a plain text. The enveloped, enveloping, or detached (as of 12.14) XML signature(s) will be set to the body of the out-message.
  • With the verifier endpoint, you can validate an enveloped or enveloping XML signature or even several detached (as of 2.14.0) XML signatures contained in the body of the in-message; if the validation is successful, then the original content is extracted from the XML signature and set to the body of the out-message.
  • The name part in the URI can be chosen by the user to distinguish between different signer/verifier endpoints within the camel context.

374.3. Basic Example

The following example shows the basic usage of the component. 

from("direct:enveloping").to("xmlsecurity:sign://enveloping?keyAccessor=#accessor",
                             "xmlsecurity:verify://enveloping?keySelector=#selector",
                             "mock:result")

In Spring XML: 

<from uri="direct:enveloping" />
    <to uri="xmlsecurity:sign://enveloping?keyAccessor=#accessor" />
    <to uri="xmlsecurity:verify://enveloping?keySelector=#selector" />
<to uri="mock:result" />

For the signing process, a private key is necessary. You specify a key accessor bean which provides this private key. For the validation, the corresponding public key is necessary; you specify a key selector bean which provides this public key.

The key accessor bean must implement the KeyAccessor interface. The package org.apache.camel.component.xmlsecurity.api contains the default implementation class DefaultKeyAccessor which reads the private key from a Java keystore.

The key selector bean must implement the javax.xml.crypto.KeySelector interface. The package org.apache.camel.component.xmlsecurity.api contains the default implementation class DefaultKeySelector which reads the public key from a keystore.

In the example, the default signature algorithm http://www.w3.org/2000/09/xmldsig#rsa-sha1 is used. You can set the signature algorithm of your choice by the option signatureAlgorithm (see below). The signer endpoint creates an enveloping XML signature. If you want to create an enveloped XML signature then you must specify the parent element of the Signature element; see option parentLocalName for more details.

For creating detached XML signatures, see sub-chapter "Detached XML Signatures as Siblings of the Signed Elements".

http://www.w3.org/2000/09/xmldsig#rsa-sha1

String

signatureId (sign)

Sets the signature Id. If this parameter is not set (null value) then a unique ID is generated for the signature ID (default). If this parameter is set to (empty string) then no Id attribute is created in the signature element.

 

String

transformMethods (sign)

Transforms which are executed on the message body before the digest is calculated. By default, C14n is added and in the case of enveloped signature (see option parentLocalName) also http://www.w3.org/2000/09/xmldsig#enveloped-signature is added at position 0 of the list. Use methods in XmlSignatureHelper to create the transform methods.

 

List

xpathsToIdAttributes (sign)

Define the elements which are signed in the detached case via XPATH expressions to ID attributes (attributes of type ID). For each element found via the XPATH expression a detached signature is created whose reference URI contains the corresponding attribute value (preceded by '#'). The signature becomes the last sibling of the signed element. Elements with deeper hierarchy level are signed first. You can also set the XPATH list dynamically via the header XmlSignatureConstants#HEADER_XPATHS_TO_ID_ATTRIBUTES. The parameter setParentLocalName(String) or setParentXpath(XPathFilterParameterSpec) for enveloped signature and this parameter for detached signature must not be set in the same configuration.

 

List

keySelector (verify)

Provides the key for validating the XML signature.

 

KeySelector

outputNodeSearch (verify)

Sets the output node search value for determining the node from the XML signature document which shall be set to the output message body. The class of the value depends on the type of the output node search. The output node search is forwarded to XmlSignature2Message.

String

removeSignatureElements (verify)

Indicator whether the XML signature elements (elements with local name Signature and namesapce http://www.w3.org/2000/09/xmldsig#) shall be removed from the document set to the output message. Normally, this is only necessary, if the XML signature is enveloped. The default value is Boolean#FALSE. This parameter is forwarded to XmlSignature2Message. This indicator has no effect if the output node search is of type DefaultXmlSignature2Message#OUTPUT_NODE_SEARCH_TYPE_DEFAULT.F

false

Boolean

secureValidation (verify)

Enables secure validation. If true then secure validation is enabled.

true

Boolean

validationFailedHandler (verify)

Handles the different validation failed situations. The default implementation throws specific exceptions for the different situations (All exceptions have the package name org.apache.camel.component.xmlsecurity.api and are a sub-class of XmlSignatureInvalidException. If the signature value validation fails, a XmlSignatureInvalidValueException is thrown. If a reference validation fails, a XmlSignatureInvalidContentHashException is thrown. For more detailed information, see the JavaDoc.

 

ValidationFailedHandler

xmlSignature2Message (verify)

Bean which maps the XML signature to the output-message after the validation. How this mapping should be done can be configured by the options outputNodeSearchType, outputNodeSearch, and removeSignatureElements. The default implementation offers three possibilities which are related to the three output node search types Default, ElementName, and XPath. The default implementation determines a node which is then serialized and set to the body of the output message If the search type is ElementName then the output node (which must be in this case an element) is determined by the local name and namespace defined in the search value (see option outputNodeSearch). If the search type is XPath then the output node is determined by the XPath specified in the search value (in this case the output node can be of type Element, TextNode or Document). If the output node search type is Default then the following rules apply: In the enveloped XML signature case (there is a reference with URI= and transform http://www.w3.org/2000/09/xmldsig#enveloped-signature), the incoming XML document without the Signature element is set to the output message body. In the non-enveloped XML signature case, the message body is determined from a referenced Object; this is explained in more detail in chapter Output Node Determination in Enveloping XML Signature Case.

 

XmlSignature2Message

xmlSignatureChecker (verify)

This interface allows the application to check the XML signature before the validation is executed. This step is recommended in http://www.w3.org/TR/xmldsig-bestpractices/#check-what-is-signed

false

Boolean

camel.component.xmlsecurity.verifier-configuration.output-node-search

Sets the output node search value for determining the node from the XML signature document which shall be set to the output message body. The class of the value depends on the type of the output node search. The output node search is forwarded to XmlSignature2Message.

 

Object

camel.component.xmlsecurity.verifier-configuration.output-node-search-type

Determines the search type for determining the output node which is serialized into the output message bodyF. See setOutputNodeSearch(Object). The supported default search types you can find in DefaultXmlSignature2Message.

The character encoding of the resulting signed XML document. If null then the encoding of the original XML document is used.

 

String

camel.component.xmlsecurity.verifier-configuration.remove-signature-elements

Indicator whether the XML signature elements (elements with local name Signature and namesapce http://www.w3.org/2000/09/xmldsig#) shall be removed from the document set to the output message. Normally, this is only necessary, if the XML signature is enveloped. The default value is Boolean#FALSE. This parameter is forwarded to XmlSignature2Message. This indicator has no effect if the output node search is of type DefaultXmlSignature2Message#OUTPUT_NODE_SEARCH_TYPE_DEFAULT.F

false

Boolean

camel.component.xmlsecurity.verifier-configuration.schema-resource-uri

Classpath to the XML Schema. Must be specified in the detached XML Signature case for determining the ID attributes, might be set in the enveloped and enveloping case.

Enables secure validation. If true then secure validation is enabled.

true

Boolean

camel.component.xmlsecurity.verifier-configuration.uri-dereferencer

If you want to restrict the remote access via reference URIs, you can set an own dereferencer. Optional parameter. If not set the provider default dereferencer is used which can resolve URI fragments, HTTP, file and XPpointer URIs. Attention: The implementation is provider dependent!

 

URIDereferencer

camel.component.xmlsecurity.verifier-configuration.validation-failed-handler

Handles the different validation failed situations. The default implementation throws specific exceptions for the different situations (All exceptions have the package name org.apache.camel.component.xmlsecurity.api and are a sub-class of XmlSignatureInvalidException. If the signature value validation fails, a XmlSignatureInvalidValueException is thrown. If a reference validation fails, a XmlSignatureInvalidContentHashException is thrown. For more detailed information, see the JavaDoc.

 

ValidationFailedHandler

camel.component.xmlsecurity.verifier-configuration.validation-failed-handler-name

Name of handler to @param validationFailedHandlerName

 

String

camel.component.xmlsecurity.verifier-configuration.xml-signature-checker

This interface allows the application to check the XML signature before the validation is executed. This step is recommended in http://www.w3.org/TR/xmldsig-bestpractices/#check-what-is-signed

 

XmlSignatureChecker

camel.component.xmlsecurity.verifier-configuration.xml-signature2-message

Bean which maps the XML signature to the output-message after the validation. How this mapping should be done can be configured by the options outputNodeSearchType, outputNodeSearch, and removeSignatureElements. The default implementation offers three possibilities which are related to the three output node search types Default, ElementName, and XPath. The default implementation determines a node which is then serialized and set to the body of the output message If the search type is ElementName then the output node (which must be in this case an element) is determined by the local name and namespace defined in the search value (see option outputNodeSearch). If the search type is XPath then the output node is determined by the XPath specified in the search value (in this case the output node can be of type Element, TextNode or Document). If the output node search type is Default then the following rules apply: In the enveloped XML signature case (there is a reference with URI= and transform http://www.w3.org/2000/09/xmldsig#enveloped-signature), the incoming XML document without the Signature element is set to the output message body. In the non-enveloped XML signature case, the message body is determined from a referenced Object; this is explained in more detail in chapter Output Node Determination in Enveloping XML Signature Case.

374.6.1. Output Node Determination in Enveloping XML Signature Case

After the validation the node is extracted from the XML signature document which is finally returned to the output-message body. In the enveloping XML signature case, the default implementation DefaultXmlSignature2Message of XmlSignature2Message does this for the node search type Default in the following way (see option xmlSignature2Message):

  • First an object reference is determined:

    • Only same document references are taken into account (URI must start with #)
    • Also indirect same document references to an object via manifest are taken into account.
    • The resulting number of object references must be 1.
  • Then, the object is dereferenced and the object must only contain one XML element. This element is returned as output node.

This does mean that the enveloping XML signature must have either the structure: 

<Signature>
      <SignedInfo>
         <Reference URI="#object"/>
         <!-- further references possible but they must not point to an Object or Manifest containing an object reference -->
         ...
      </SignedInfo>

      <Object Id="object">
           <!-- contains one XML element which is extracted to the message body -->
      <Object>
      <!-- further object elements possible which are not referenced-->
      ...
      (<KeyInfo>)?
</Signature>

or the structure: 

<Signature>
      <SignedInfo>
         <Reference URI="#manifest"/>
         <!-- further references  are possible but they must not point to an Object or other manifest containing an object reference -->
         ...
      </SignedInfo>

      <Object >
         <Manifest Id="manifest">
            <Reference URI=#object/>
         </Manifest>
      </Objet>
      <Object Id="object">
          <!-- contains the DOM node which is extracted to the message body -->
      </Object>
       <!-- further object elements possible which are not referenced -->
      ...
      (<KeyInfo>)?
</Signature>

374.7. Detached XML Signatures as Siblings of the Signed Elements

Since 2.14.0

You can create detached signatures where the signature is a sibling of the signed element. The following example contains two detached signatures. The first signature is for the element C and the second signature is for element A. The signatures are nested; the second signature is for the element A which also contains the first signature.

Example Detached XML Signatures 

<?xml version="1.0" encoding="UTF-8" ?>

    <A ID="IDforA">
        <B>
            <C ID="IDforC">

        <ds:SignatureValue>q3tvRoGgc8cMUqUSzP6C21zb7tt04riPnDuk=</ds:SignatureValue>
    </ds:Signature>
<root>

The example shows that you can sign several elements and that for each element a signature is created as sibling. The elements to be signed must have an attribute of type ID. The ID type of the attribute must be defined in the XML schema (see option schemaResourceUri). You specify a list of XPATH expressions pointing to attributes of type ID (see option xpathsToIdAttributes). These attributes determine the elements to be signed. The elements are signed by the same key given by the keyAccessor bean. Elements with higher (i.e. deeper) hierarchy level are signed first. In the example, the element C is signed before the element A.

Java DSL Example 

from("direct:detached")
  .to("xmlsecurity:sign://detached?keyAccessor=#keyAccessorBeant&xpathsToIdAttributes=#xpathsToIdAttributesBean&schemaResourceUri=Test.xsd")
  .to("xmlsecurity:verify://detached?keySelector=#keySelectorBean&schemaResourceUri=org/apache/camel/component/xmlsecurity/Test.xsd")
  .to("mock:result");

374.8. XAdES-BES/EPES for the Signer Endpoint

Available as of Camel 2.15.0 

XML Advanced Electronic Signatures (XAdES) defines extensions to XML Signature. This standard was defined by the European Telecommunication Standards Institute and allows you to create signatures which are compliant to the European Union Directive (1999/93/EC) on a Community framework for electronic signatures. XAdES defines different sets of signature properties which are called signature forms. We support the signature forms Basic Electronic Signature (XAdES-BES) and Explicit Policy Based Electronic Signature (XAdES-EPES) for the Signer Endpoint. The forms Electronic Signature with Validation Data XAdES-T and XAdES-C are not supported.

We support the following properties of the XAdES-EPES form ("?" denotes zero or one occurrence):

Supported XAdES-EPES Properties 

<QualifyingProperties Target>
    <SignedProperties>
        <SignedSignatureProperties>
            (SigningTime)?
            (SigningCertificate)?
            (SignaturePolicyIdentifier)
            (SignatureProductionPlace)?
            (SignerRole)?
        </SignedSignatureProperties>
        <SignedDataObjectProperties>
            (DataObjectFormat)?
            (CommitmentTypeIndication)?
        </SignedDataObjectProperties>
    </SignedProperties>
</QualifyingProperties>

The properties of the XAdES-BES form are the same except that the SignaturePolicyIdentifier property is not part of XAdES-BES. 

You can configure the XAdES-BES/EPES properties via the bean org.apache.camel.component.xmlsecurity.api.XAdESSignatureProperties or org.apache.camel.component.xmlsecurity.api.DefaultXAdESSignatureProperties. XAdESSignatureProperties does support all properties mentioned above except the SigningCertificate property. To get the SigningCertificate property, you must overwrite either the method XAdESSignatureProperties.getSigningCertificate() or XAdESSignatureProperties.getSigningCertificateChain(). The class DefaultXAdESSignatureProperties overwrites the method getSigningCertificate() and allows you to specify the signing certificate via a keystore and alias. The following example shows all parameters you can specify. If you do not need certain parameters you can just omit them.
