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

Before you begin this task, you must configure the key information that is referenced by the key information references in the encryption information panel. For more information, see Configuring the key information for the consumer binding on the application level.
This task provides the steps that are needed for configuring the encryption information for the request consumer (server side) and response consumer (client side) bindings at the application level. The encryption information on the consumer side is used for decrypting the encrypted message parts in the incoming Simple Object Access Protocol (SOAP) message.

Complete the following steps to configure the encryption information for the request consumer or response consumer section of the bindings file on the application level:

  1. Locate the Encryption information configuration panel in the administrative console.
    1. Click Applications > Enterprise applications > application_name.
    2. Under Related Items, click EJB Modules or Web Modules > URI_name.
    3. Under Additional properties you can access the encryption information for the request consumer and response consumer bindings.
      • For the request consumer (receiver) binding, click Web services: Server security bindings. Under Request consumer (receiver) binding, click Edit custom.
      • For the response consumer (receiver) binding, click Web services: Client security bindings. Under Response consumer (receiver) binding, click Edit custom.
    4. Under Required properties, click Encryption information.
    5. Click New to create an encryption information configuration, click Delete to delete an existing configuration, or click the name of an existing encryption information configuration to edit its settings. If you are creating a new configuration, enter a name in the Encryption information name field. For example, you might specify cons_encinfo.
  2. Select a data encryption algorithm from the Data encryption algorithm field. The data encryption algorithm is used for encrypting or decrypting parts of a SOAP message such as the SOAP body or the username token. WebSphere® Application Server supports the following pre-configured algorithms:

    The data encryption algorithm that you select for the consumer side must match the data encryption method that you select for the generator side.

  3. Select a key encryption algorithm from the Key encryption algorithm field. The key encryption algorithm is used for encrypting the key that is used for encrypting the message parts within the SOAP message. Select (none) if the data encryption key, which is the key that is used for encrypting the message parts, is not encrypted. WebSphere Application Server supports the following pre-configured algorithms:
    • http://www.w3.org/2001/04/xmlenc#rsa-1_5
    • http://www.w3.org/2001/04/xmlenc#kw-tripledes
    • http://www.w3.org/2001/04/xmlenc#kw-aes128
    • http://www.w3.org/2001/04/xmlenc#kw-aes256

      To use the http://www.w3.org/2001/04/xmlenc#aes256-cbc algorithm, you must download the unrestricted Java Cryptography Extension (JCE) policy file from the following Web site: http://www.ibm.com/developerworks/java/jdk/security/index.html.

    • http://www.w3.org/2001/04/xmlenc#kw-aes192

      To use the http://www.w3.org/2001/04/xmlenc#kw-aes192 algorithm, you must download the unrestricted Java Cryptography Extension (JCE) policy file from the following Web site: http://www.ibm.com/developerworks/java/jdk/security/index.html.

    The key encryption algorithm that you select for the consumer side must match the key encryption method that you select for the generator side.

  4. Optional: Select a part reference in the Part reference field. The part reference specifies the name of the message part that is encrypted and is defined in the deployment descriptor. For example, you can encrypt the bodycontent message part in the deployment descriptor. The name of this Required Confidentiality part is conf_con. This message part is shown as an option in the Part reference field.
  5. Under Additional properties, click Key information references.
  6. Click New to create a key information configuration, click Delete to delete an existing configuration, or click the name of an existing key information configuration to edit its settings. If you are creating a new configuration, enter a name in the name field. For example, you might specify con_ekeyinfo. This entry is the name of the <encryptionKeyInfo> element in the binding file.
  7. Select a key information reference from the Key information reference field. This reference is the value of the keyinfoRef attribute of the <encryptionKeyInfo> element and it is the name of the <keyInfo> element that is referenced by this key information reference. Each key information reference entry generates an <encryptionKeyInfo> element under the <encryptionInfo> element in the binding configuration file. For example, if you enter con_ekeyinfo in the Name field and dec_keyinfo in the Key information reference field, the following <encryptionKeyInfo> element is generated in the binding file:
    <encryptionKeyInfo xmi:id="EncryptionKeyInfo_1085092248843"
keyinfoRef="dec_keyinfo”  name="con_ekeyinfo"/>
  8. Click OK and then click Save to save the configuration.
You have configured the encryption information for the consumer binding at the application level
You must specify a similar encryption information configuration for the generator.
