Tuning WS-Security for V5.x applications


The JCE policy is integrated into the IBM SDK V1.4.x and is no longer an optional package. However, due to export and import regulations, the default JCE jurisdiction policy file shipped with the SDK enables you to use strong, but limited, cryptography only.

To enforce this default policy, WAS uses a JCE jurisdiction policy file that might introduce a performance impact. The default JCE jurisdiction policy might have a performance impact on the cryptographic functions that are supported by Web services security. If we have Web services applications that use TLS for XML encryption or digital signatures, we might encounter performance degradation over previous releases of WAS. However, IBM and Sun Microsystems provide versions of these jurisdiction policy files that do not have restrictions on cryptographic strengths. If permitted by the governmental import and export regulations, download one of these jurisdiction policy files. After downloading one of these files, the performance of JCE and Web Services security might improve.

 

  1. [AIX] [Linux]

    (Windows) For WAS platforms using IBM Developer Kit, Java Technology Edition V 1.4.2, including the AIX, Linux, and Windows platforms, we can obtain unlimited jurisdiction policy files by completing the following steps:

    1. Go to the following Web site: http://www.ibm.com/developerworks/java/jdk/security/IBM_HTTP_Server_v735.html.

    2. Click Java 1.4.2.

    3. Click IBM SDK Policy files. The Unrestricted JCE Policy files for SDK 1.4 Web site is displayed.

    4. Enter the user ID and password or register with IBM to download the policy files.

      The policy files are downloaded onto the machine.

  2. [HP-UX] For WAS platforms using the Sun-based Java SE Development Kit 6 (JDK 6) V1.4.2, including the Solaris environments and the HP-UX platform, we can obtain unlimited jurisdiction policy files by completing the following steps:

    1. Go to the following Web site: http://java.sun.com/j2se/1.4.2/download.html.

    2. Click Other Downloads.

    3. Locate the JCE Unlimited Strength Jurisdiction Policy Files 1.4.2 information and click Download. The policy files are downloaded onto the machine.
