XML Security

Since Camel 2.0

The XMLSecurity Data Format facilitates encryption and decryption of XML payloads at the Document, Element, and Element Content levels (including simultaneous multi-node encryption/decryption using XPath). To sign messages using the XML Signature specification, please see the Camel XML Security component.

The encryption capability is based on formats supported using the Apache XML Security (Santuario) project. Symmetric encryption/decryption is currently supported using Triple-DES and AES (128, 192, and 256) encryption formats. Additional formats can be easily added later as needed. This capability allows Camel users to encrypt/decrypt payloads while being dispatched or received along a route.

Since Camel 2.9
The XMLSecurity Data Format supports asymmetric key encryption. In this encryption model a symmetric key is generated and used to perform XML content encryption or decryption. This "content encryption key" is then itself encrypted using an asymmetric encryption algorithm that leverages the recipient’s public key as the "key encryption key". Use of an asymmetric key encryption algorithm ensures that only the holder of the recipient’s private key can access the generated symmetric encryption key. Thus, only the private key holder can decode the message. The XMLSecurity Data Format handles all of the logic required to encrypt and decrypt the message content and encryption key(s) using asymmetric key encryption.

The XMLSecurity Data Format also has improved support for namespaces when processing the XPath queries that select content for encryption. A namespace definition mapping can be included as part of the data format configuration. This enables true namespace matching, even if the prefix values in the XPath query and the target xml document are not equivalent strings.

XMLSecurity Options

The XML Security dataformat supports 12 options, which are listed below.

The XPath reference to the XML Element selected for encryption/decryption. If no tag is specified, the entire payload is encrypted/decrypted.

secureTagContents

false

Boolean

A boolean value to specify whether the XML Element is to be encrypted or the contents of the XML Element. false = Element Level. true = Element Content Level.

keyCipherAlgorithm

RSA_OAEP

Enum

  • RSA_v1dot5

  • RSA_OAEP

  • RSA_OAEP_11

recipientKeyAlias

String

The key alias to be used when retrieving the recipient’s public or private key from a KeyStore when performing asymmetric key encryption or decryption.

Key Cipher Algorithm

The default Key Cipher Algorithm is now XMLCipher.RSA_OAEP instead of XMLCipher.RSA_v1dot5. Usage of XMLCipher.RSA_v1dot5 is discouraged due to various attacks. Requests that use RSA v1.5 as the key cipher algorithm will be rejected unless it has been explicitly configured as the key cipher algorithm.

Marshal

In order to encrypt the payload, the marshal processor needs to be applied on the route followed by the xmlSecurity() tag.

Unmarshal

In order to decrypt the payload, the unmarshal processor needs to be applied on the route followed by the xmlSecurity() tag.

Examples

Given below are several examples of how marshalling could be performed at the Document, Element, and Content levels.

Full Payload encryption/decryption

KeyGenerator keyGenerator = KeyGenerator.getInstance("AES");
keyGenerator.init(256);
Key key = keyGenerator.generateKey();

from("direct:start")
    .marshal().xmlSecurity(key.getEncoded())
    .unmarshal().xmlSecurity(key.getEncoded()
    .to("direct:end");

Partial Payload Content Only encryption/decryption with choice of passPhrase(password)

String tagXPATH = "//cheesesites/italy/cheese";
boolean secureTagContent = true;
...
String passPhrase = "Just another 24 Byte key";
from("direct:start")
    .marshal().xmlSecurity(tagXPATH, secureTagContent, passPhrase)
    .unmarshal().xmlSecurity(tagXPATH, secureTagContent, passPhrase)
    .to("direct:end");

Partial Payload Content Only encryption/decryption with passPhrase(password) and Algorithm

import org.apache.xml.security.encryption.XMLCipher;
....
String tagXPATH = "//cheesesites/italy/cheese";
boolean secureTagContent = true;

    .unmarshal().xmlSecurity(tagXPATH, secureTagContent, passPhrase, algorithm)
    .to("direct:end");

Partial Payload Content with Namespace support

Java DSL

final Map<String, String> namespaces = new HashMap<String, String>();
namespaces.put("cust", "http://cheese.xmlsecurity.camel.apache.org/");

final KeyStoreParameters tsParameters = new KeyStoreParameters();
tsParameters.setPassword("password");
tsParameters.setResource("sender.truststore");

context.addRoutes(new RouteBuilder() {
    public void configure() {
        from("direct:start")
           .marshal().xmlSecurity("//cust:cheesesites/italy", namespaces, true, "recipient",
                                testCypherAlgorithm, XMLCipher.RSA_v1dot5, tsParameters)
           .to("mock:encrypted");
    }
}

Dependencies

This data format is provided within the camel-xmlsecurity component.

Spring Boot Auto-Configuration

When using xmlSecurity with Spring Boot make sure to use the following Maven dependency to have support for auto configuration:

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

The component supports 62 options, which are listed below.

Name Description Default Type

camel.component.xmlsecurity-sign.add-key-info-reference

In order to protect the KeyInfo element from tampering you can add a reference to the signed info element so that it is protected via the signature value. The default value is true. Only relevant when a KeyInfo is returned by KeyAccessor. and KeyInfo#getId() is not null.

true

Boolean

camel.component.xmlsecurity-sign.autowired-enabled

Whether autowiring is enabled. This is used for automatic autowiring options (the option must be marked as autowired) by looking up in the registry to find if there is a single instance of matching type, which then gets configured on the component. This can be used for automatic configuring JDBC data sources, JMS connection factories, AWS Clients, etc.

true

Boolean

camel.component.xmlsecurity-sign.base-uri

You can set a base URI which is used in the URI dereferencing. Relative URIs are then concatenated with the base URI.

String

camel.component.xmlsecurity-sign.canonicalization-method

Canonicalization method used to canonicalize the SignedInfo element before the digest is calculated. You can use the helper methods XmlSignatureHelper.getCanonicalizationMethod(String algorithm) or getCanonicalizationMethod(String algorithm, List inclusiveNamespacePrefixes) to create a canonicalization method. The option is a javax.xml.crypto.AlgorithmMethod type.

AlgorithmMethod

camel.component.xmlsecurity-sign.clear-headers

Determines if the XML signature specific headers be cleared after signing and verification. Defaults to true.

true

Boolean

camel.component.xmlsecurity-sign.content-object-id

String

camel.component.xmlsecurity-sign.content-reference-type

Type of the content reference. The default value is null. This value can be overwritten by the header XmlSignatureConstants#HEADER_CONTENT_REFERENCE_TYPE.

String

camel.component.xmlsecurity-sign.content-reference-uri

Reference URI for the content to be signed. Only used in the enveloped case. If the reference URI contains an ID attribute value, then the resource schema URI ( setSchemaResourceUri(String)) must also be set because the schema validator will then find out which attributes are ID attributes. Will be ignored in the enveloping or detached case.

String

camel.component.xmlsecurity-sign.crypto-context-properties

Sets the crypto context properties. See \{link XMLCryptoContext#setProperty(String, Object)}. Possible properties are defined in XMLSignContext an XMLValidateContext (see Supported Properties).

URIDereferencer

camel.component.xmlsecurity-sign.xpaths-to-id-attributes

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.

XmlSignatureChecker

camel.component.xmlsecurity-verify.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. The option is a org.apache.camel.component.xmlsecurity.api.XmlSignature2Message type.
