Encryption information name

Name for the encryption information.

Data type	String

Data encryption algorithm

Algorithm Uniform Resource Identifier (URI) of the data encryption method.

The following algorithms are supported:

• 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. See Encryption information configuration settings: Methods.
• http://www.w3.org/2001/04/xmlenc#aes192-cbc. To use this algorithm, download the unrestricted JCE policy file from the following website: http://www.ibm.com/developerworks/java/jdk/security/index.html. See the help topic Encryption information configuration settings: Methods.

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

By default, the Java Cryptography Extension (JCE) is shipped with restricted or limited strength ciphers. To use 192-bit and 256-bit Advanced Encryption Standard (AES) encryption algorithms, apply unlimited jurisdiction policy files. See the Key encryption algorithm field description.

Key locator reference

Name of the key locator configuration that retrieves the key for XML digital signature and XML encryption.

The Key locator reference field is displayed for the request receiver and response receiver bindings.

We can configure these key locator reference options on the server level, the cell level, and the application level. The configurations that are listed in the field are a combination of the configurations on these three levels.

We can specify an encryption key configuration for the following bindings on the following levels:

Key encryption algorithm

Algorithm Uniform Resource Identifier (URI) of the key encryption method.

The following algorithms are provided by the application server:

• 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 or later.

  By default, the RSA-OAEP algorithm uses the SHA1 message digest algorithm to compute a message digest as part of the encryption operation. Optionally, you can use the SHA256 or SHA512 message digest algorithm by specifying a key encryption algorithm property. The property name is: com.ibm.wsspi.wssecurity.enc.rsaoaep.DigestMethod. The property value is one of the following URIs of the digest method:

  • http://www.w3.org/2001/04/xmlenc#sha256
  • http://www.w3.org/2001/04/xmlenc#sha512

  By default, the RSA-OAEP algorithm uses a null string for the optional encoding octet string for the OAEPParams. We can provide an explicit encoding octet string by specifying a key encryption algorithm property. For the property name, you can specify com.ibm.wsspi.wssecurity.enc.rsaoaep.OAEPparams. The property value is the base 64-encoded value of the octet string.

  We can set these digest method and OAEPParams properties on the generator side only. On the consumer side, these properties are read from the incoming SOAP message.

• http://www.w3.org/2001/04/xmlenc#kw-aes128
• http://www.w3.org/2001/04/xmlenc#kw-aes192

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

Application server platforms and IBM Developer Kit, Java Technology Edition v1.4.2

By default, the Java Cryptography Extension (JCE) ships with restricted or limited strength ciphers. To use 192-bit and 256-bit Advanced Encryption Standard (AES) encryption algorithms, apply unlimited jurisdiction policy files.

Before downloading these policy files, back up the existing policy files (local_policy.jar and US_export_policy.jar in...

WAS_HOME/java/jre/lib/security/

) prior to overwriting them in case to restore the original files later.

Attention: Fix packs that include updates to the SDK might overwrite unrestricted policy files. Back up unrestricted policy files before you apply a fix pack and reapply these files after the fix pack is applied.

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.

To download the policy files, complete one of the following sets of steps:

• (AIX) (Windows) For application server platforms using IBM Developer Kit, Java Technology Edition Version 1.4.2, including the AIX, Linux, and Windows platforms, complete the following steps to obtain unlimited jurisdiction policy files:
  1. Go to the following website: IBM developer works: Security Information

  2. Click Java 1.4.2

  3. Click IBM SDK Policy files.

     The Unrestricted JCE Policy files for SDK 1.4 website is displayed.

  4. Enter your user ID and password or register with IBM to download the policy files. The policy files are downloaded onto your machine.

• (Solaris) For application server platforms using the Sun-based Java SE Development Kit 6 (JDK 6) v1.4.2, including the Solaris environments and the HP-UX platform, complete the following steps to obtain unlimited jurisdiction policy files:
  1. Go to the following website: Download , v 1.4.2 (Java EE)

  2. Click Archive area.
  3. Locate the Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files 1.4.2 information and click Download. The policy file is downloaded onto your machine.

After following either of these sets of steps, two JAR files are placed in the Java virtual machine (JVM) jre/lib/security/ directory.
