Data type

String

Data encryption algorithm

Specify the algorithm 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 Web site: http://www.ibm.com/developerworks/java/jdk/security/index.html. For more information, 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 Web site: http://www.ibm.com/developerworks/java/jdk/security/index.html. For more information, see Encryption information configuration settings: Methods.

  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. For more information, 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, which are used by V5.x applications.

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

Binding name	Serverlevel, cell level, or application level	Path
Default generator binding	Cell level	Click Security > Web services. Under Additional properties, click Key locators.
Default consumer bindings	Cell level	Click Security > Web services. Under Additional properties, click Key locators.
Default generator binding	Server level	Click Servers > Application servers > server. Under Security, click Web services: Default bindings for Web services security. Under Additional properties, click Key locators.
Default consumer binding	Server level	Click Servers > Application servers > server. Under Security, click Web services: Default bindings for Web services security. Under Additional properties, click Key locators.

Response receiver	Application level	Click Applications > Enterprise applications > application. Click Manage modules> URI_name. Click Web services: Client security bindings. Under Response receiver binding, click Edit. Under Additional properties, click Key locators.

Key encryption algorithm

Specify the algorithm URI of the key encryption method. The following algorithms are provided by the appserver:

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

  When running with Software Development Kit (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 Software Development Kit (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. You 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.

  You 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#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-aes192

  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).
