Configuring signing information for the generator binding with an assembly tool

Prior to completing this task, you must complete the following steps:
  1. Specify which message parts to digitally sign. For more information, see Signing message elements in generator security constraints with keywords or Signing message elements in generator security constraints with an XPath expression.
  2. Configure the key information that is referenced by the Key information element within the Signing information dialog window. For more information, see Configuring key information for the generator binding.

Complete the following steps to configure the signing information for the server-side and client-side bindings using an assembly tool. The request generator is configured for the client and the response generator is configured for the server. In the following steps, you must configure either the client-side bindings in step 2 or the server-side bindings in step 3.

  1. Click Window > Open Perspective > J2EE.
  2. Optional: Locate the client-side bindings using the Project Explorer window. The Client Deployment Descriptor window is displayed. This Web service contains the bindings that you need to configure.
    1. Expand the Web Services > Client section and double-click the name of the Web service.
    2. Click the WS Binding tab and expand the Security Request Generator Binding Configuration section.
  3. Optional: Locate the server-side bindings using the Project Explorer window. The Web Services Editor window is displayed. This Web service contains the bindings that you need to configure.
    1. Expand the Web Services > Services section and double-click the name of the Web service.
    2. Click the Binding Configurations tab and expand the Response Generator Binding Configuration Details section.
  4. Expand the Signing Information section and click Add to add a new entry or select an existing entry and click Edit. The Signing Information dialog window is displayed.
    1. Specify a name for the signing information configuration in the Signing information name field. For example, you might specify gen_signinfo.
    2. Select a canonicalization method from the Canonicalization method algorithm field. The canonicalization method algorithm is used to canonicalize the signing information before it is digested as part of the signature operation. The following pre-configured algorithms are supported:
      • http://www.w3.org/2001/10/xml-exc-c14n#
      • http://www.w3.org/2001/10/xml-exc-c14n#WithComments
      • http://www.w3.org/TR/2001/REC-xml-c14n-20010315
      • http://www.w3.org/TR/2001/REC-xml-c14n-20010315#WithComments

      You must specify the same canonicalization algorithm for both the generator and the consumer. For more information on configuring the signing information for the consumer, see Configuring signing information for the consumer binding.

    3. Select a signature method algorithm from the Signature method algorithm field. The following pre-configured algorithms are supported:
      • http://www.w3.org/2000/09/xmldsig#rsa-sha1
      • http://www.w3.org/2000/09/xmldsig#dsa-sha1
      • http://www.w3.org/2000/09/xmldsig#hmac-sha1

      You must specify the same canonicalization algorithm for both the generator and the consumer. For more information on configuring the signing information for the consumer, see Configuring signing information for the consumer binding.

  5. Click Add in the Signing Key Information section to add a new key information entry or click Remove to delete a selected entry. Complete the following substeps if you are adding a new key information entry.
    1. Specify a name in the Key information name field. For example, you might specify gen_skeyinfo.
    2. Select a key information reference from the list under the Key information element field. The value in this field references the key information configuration that you specified previously. If you have a key information configuration called gen_signkeyinfo that you want to use with this signing information configuration, specify gen_signkeyinfo in the Key information element field. For more information, see Configuring key information for the generator binding.
    3. Optional: Select the Use key information signature option if you want to sign the key information within the Simple Object Access Protocol (SOAP) message.
    4. Optional: Select a key information signature type from the Type field if you select the Use key information signature option. Select the keyinfo value to specify that the entire KeyInfo element must be signed within the SOAP message. Select the keyinfochildelements value to specify that the child elements within the KeyInfo element must be signed, but the KeyInfo element itself does not need to be signed.
  6. Click OK to save your signing information configuration.
  7. Expand the Part References subsection and select the signing information configuration from the Signing Information section.
  8. Click Add in the Part References subsection to add a new entry or select an existing entry and click Edit. The Part References dialog window is displayed.
    1. Specify a name for the part reference configuration in the Part reference name field.
    2. Select a integrity part configuration in the Integrity part field. For more information on how to configure the integrity part, see Signing message elements in generator security constraints with keywords or Signing message elements in generator security constraints with an XPath expression.
    3. Select the http://www.w3.org/2000/09/xmldsig#sha1 digest method algorithm in the Digest method algorithm field. This digest method algorithm is used to create the digest for each message part that is specified by this part reference.
    4. Expand the Transforms subsection and the part reference configuration from the Part reference subsection.
    5. Click Add in the Transforms subsection to add a new entry or select an existing entry and click Edit. The Transform dialog window is displayed.
    6. Specify a transform name in the Name field. For example, you might specify reqint_body_transform1.
    7. Select a transform algorithm from the Algorithm field. The following transform algorithms are supported:
      http://www.w3.org/2001/10/xml-exc-c14n#
      This algorithm specifies the World Wide Web Consortium (W3C) Exclusive Canonicalization recommendation.
      http://www.w3.org/TR/1999/REC-xpath-19991116
      This algorithm specifies the W3C XML path language recommendation. If you specify this algorithm, you must specify the property name and value by clicking Properties, which is displayed under Additional properties. For example, you might specify the following information:
      Property
      com.ibm.wsspi.wssecurity.dsig.XPathExpression
      Value
      not(ancestor-or-self::*[namespace-uri()='http://www.w3.org/2000/09/xmldsig#' and local-name()='Signature'])
      http://www.w3.org/2002/06/xmldsig-filter2
      This algorithm specifies the XML-Signature XPath Filter Version 2.0 proposed recommendation.
      When you use this algorithm, you must specify a set of properties in the Transform property fields. You can use multiple property sets for the XPath Filter Version 2. Thus, it is recommended that your property names end with the number of the property set, which is denoted by an asterisk in the following examples:
      • To specify an XPath expression for the XPath filter2, you might use:

        name com.ibm.wsspi.wssecurity.dsig.XPath2Expression_*

      • To specify a filter type for each XPath, you might use:

        name com.ibm.wsspi.wssecurity.dsig.XPath2Filter_*

        Following this expression, you can have a value, [intersect], [subtract], or [union].
      • To specify the processing order for each XPath, you might use:

        name com.ibm.wsspi.wssecurity.dsig.XPath2Order_*

        Following this expression, indicate the processing order of the XPath.
      The following is a list of complete examples:

      com.ibm.wsspi.wssecurity.dsign.XPath2Filter_1 = [intersect]
      com.ibm.wsspi.wssecurity.dsign.XPath2Order_1 = [1]
      com.ibm.wsspi.wssecurity.dsign.XPath2Expression_2 = [XPath expression#2]
      com.ibm.wsspi.wssecurity.dsign.XPath2Filter_2 = [subtract]
      com.ibm.wsspi.wssecurity.dsign.XPath2Filter_2 = [1]

      http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#STR-Transform
      http://www.w3.org/2002/07/decrypt#XML
      This algorithm specifies the W3C decryption transform for XML Signature recommendation.
      http://www.w3.org/2000/09/xmldsig#enveloped-signature
      This algorithm specifies the W3C recommendation for XML digital signatures.

      The transform algorithm that you select for the generator must match the transform algorithm for the consumer.

After you complete this task for the generator binding, you must configure the signing information for consumer binding.
