Configure encryption to protect message confidentiality at the server level

The encryption information for the default consumer specifies how to process the encryption information on the receiver side if these bindings are not defined at the application level. WebSphere Application Server provides default values for the bindings. However, an administrator must modify the defaults for a production environment. To configure the encryption information for the consumer binding on the server level:

  1. Access the default bindings for the server level.

    1. Click Servers > Server Types > WebSphere application servers > server_name.

    2. Under Security, click JAX-WS and JAX-RPC security runtime.

      In a mixed node cell with a server using WAS v6.1 or earlier, click Web services: Default bindings for Web Services Security.

  2. Under Default consumer bindings, click Encryption information.

  3. 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 the settings. If you are creating a new configuration, enter a unique name for the encryption configuration in the Encryption information name field. For example, you might specify con_encinfo.

    If you create more than one encryption information configuration, the WS-Security runtime environment only honors the first configuration listed in the bindings file.

  4. Select a data encryption algorithm from the Data encryption algorithm field. This algorithm is used to encrypt the data. WAS supports the following pre-configured algorithms:

    • http://www.w3.org/2001/04/xmlenc#tripledes-cbc
    • http://www.w3.org/2001/04/xmlenc#aes128-cbc
    • http://www.w3.org/2001/04/xmlenc#aes256-cbc

      To use this algorithm, download the unrestricted Java Cryptography Extension (JCE) policy file from the following website: http://www.ibm.com/developerworks/java/jdk/security/index.html.

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

      To use this algorithm, download the unrestricted Java Cryptography Extension (JCE) policy file from the following website: http://www.ibm.com/developerworks/java/jdk/security/index.html.

      Restriction: Do not use the 192-bit key encryption algorithm if we want our configured application to be in compliance with the Basic Security Profile (BSP).

      Your country of origin might have restrictions on the import, possession, use, or re-export to another country, of encryption software. Before downloading or using the unrestricted policy files, check the laws of your country, its regulations, and its policies concerning the import, possession, use, and re-export of encryption software, to determine if it is permitted.

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

  5. Select a key encryption algorithm from the Key encryption algorithm field. This algorithm is used to encrypt the key. WAS supports the following pre-configured algorithms:

    • http://www.w3.org/2001/04/xmlenc#rsa-oaep-mgf1p.

      When running with SDK v1.4, the list of supported key transport algorithms does not include this one. This algorithm appears in the list of supported key transport algorithms when running with SDK v1.5.

      Restriction: This algorithm is not supported when the WAS is running in Federal Information Processing Standard (FIPS) mode.

    • 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 this algorithm, download the unrestricted Java Cryptography Extension (JCE) policy file from the following website: http://www.ibm.com/developerworks/java/jdk/security/index.html.

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

      To use this algorithm, download the unrestricted Java Cryptography Extension (JCE) policy file from the following website: http://www.ibm.com/developerworks/java/jdk/security/index.html.

      Restriction: Do not use the 192-bit key encryption algorithm if we want our configured application to be in compliance with the Basic Security Profile (BSP).

    If you select None, the key is not encrypted.

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

  6. Under Additional properties, click Key information references.

  7. 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 the settings. If you are creating a new configuration, enter a unique name for the key information configuration in the name field. For example, you might specify con_enckeyinfo.

  8. Select a key information reference from the Key information reference field. This selection refers to the name of the key information used for encryption. For more information, see Configure the key information for the consumer binding using JAX-RPC on the server level.

  9. Click OK and Save to save the configuration.
