Configuring the signing information for the consumer binding on the application level

In the server-side extensions file and the client-side deployment descriptor extensions file, specify which parts of the message are signed. Also, you need to configure the key information that is referenced by the key information references on the signing information panel within the WebSphere® Application Server administrative console.

This task explains the steps that are needed for you to configure the signing information for the server-side request consumer and the client-side response consumer bindings at the application level. WAS uses the signing information on the consumer side to verify the integrity of the received Simple Object Access Protocol (SOAP) message by validating that the message parts are signed. Complete the following steps to configure the signing information for the server-side request consumer and client-side response consumer sections of the bindings files on the application level:

  1. Access the WAS administrative console. To access the administrative console, enter http://localhost:9060/ibm/console in your Web browser unless you have changed the port number.

  2. Click Applications > Enterprise applications > application_name.

  3. Under Related Items, click either Web modules or EJB Modules > URI_name.

  4. Access the server security bindings or the client security bindings.

    • To configure the request consumer signing information, click Web services: Server security bindings. Under Request consumer (receiver) binding, click Edit custom.

    • To configure the response consumer signing information, click Web services: Client security bindings. Under Response consumer (receiver) binding, click Edit custom.

  5. Under Required properties, click Signing information.

  6. Click New to create a signing information configuration, click Delete to delete an existing configuration, or click the name of an existing signing information configuration to edit its settings. If you are creating a new configuration, enter a name in the Signing information name field.

  7. Select a signature method algorithm from the Signature method field. The signature method is the algorithm that is used to convert the canonicalized <SignedInfo> element in the binding file into the <SignatureValue> element. The algorithm that is specified for the consumer, which is either the request consumer or the response consumer configuration, must match the algorithm specified for the generator, which is either the request generator or response generator configuration. WAS supports the following pre-configured algorithms:

  8. Select a canonicalization method from the Canonicalization method field. The canonicalization method algorithm is used to canonicalize the <SignedInfo> element before it is incorporated as part of the digital signature operation. The canonicalization algorithm that you specify for the generator must match the algorithm for the consumer. WAS supports the following pre-configured algorithms:

  9. Select a key information signature type from the Key information signature type field. The key information signature type specifies how the <KeyInfo> element in the SOAP message is digitally signed. WAS supports the following signature types:

    None

    Specifies that the key is not signed.

    Keyinfo

    Specifies that the entire KeyInfo element is signed.

    Keyinfochildelements

    Specifies that the child elements of the KeyInfo element are signed.

    If you do not specify one of the previous signature types, WAS uses keyinfo, by default. The key information signature type for the consumer must match the signature type for the generator.

  10. Under Additional properties, click Key information references.

    1. Click New to create a key information reference or click the name of an existing entry to edit its configuration. The Key information references panel is displayed.

    2. Enter a name in the Name field.

    3. Select a key information reference in the Key information reference field. This reference is the key information configuration name that specifies the key information that is used by this signing information configuration.

  11. Return to the Signing information panel. Under Additional properties, click Part references. On the Part references panel, you can specify references to the message parts that are defined in the deployment descriptor extensions file.

    1. Click New to create a new Part reference or click the name of an existing part reference to edit its configuration. The Part reference panel is displayed.

    2. Enter a name in the Part name field. This name is the name of the required integrity configuration in the deployment descriptor extensions file and specifies the message parts that must be digitally signed.

    3. Select a digest method algorithm from the Digest method algorithm field. WAS supports the following pre-configured algorithm: http://www.w3.org/200/09/xmldsig#sha1

  12. Under Additional properties, click Transforms.

    1. Click New to create a new transform or click the name of an existing transform to edit its configuration.

    2. Enter a name in the Transform name field.

    3. Select a transform algorithm from the Transform algorithm field. WAS supports the following pre-configured algorithms:

      • http://www.w3.org/2001/10/xml-exc-c14n#

      • http://www.w3.org/TR/1999/REC-xpath-19991116

      • http://www.w3.org/2002/06/xmldsig-filter2

      • 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

      • http://www.w3.org/2000/09/xmldsig#enveloped-signature

      The transform algorithm that you select for the consumer must match the transform algorithm that you select for the generator. For each part reference in the signing information, specify both a digest method algorithm and a transform algorithm.

  13. Click OK.

  14. Click Save at the top of the panel to save your configuration.

After completing these steps, you have configured the signing information for the consumer.

You must specify a similar signing information configuration for the generator.
