Algorithm mapping settings

To view a list of custom uniform resource identifier (URI) algorithms for digest value calculation, signature, key encryption, and data encryption. The appserver maps these algorithms to an implementation of the algorithm factory engine interface. With algorithm mappings, service providers can extend the cryptographic algorithms for XML digital signature and XML encryption.

To view this admin console page on 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 Websphere Application Server version 6.1 or earlier, click Web services: Default bindings for WS-Security

3. Under Additional properties, click Algorithm mappings > algorithm_factory_engine_class_name.

   The Algorithm mappings feature is not supported when the Use the FIPS option has been selected on the SSL certificate and key management panel of the admin console. When this option is selected, the New button in the Algorithm mappings panel is not available.

4. Click New.

To view this admin console page on the cell level:

1. Click Security > JAX-WS and JAX-RPC security runtime, or Services > JAX-WS and JAX-RPC security runtime.

2. Under Additional properties, click Algorithm mappings > algorithm_factory_engine_class_name.

3. Click New.

Algorithm factory engine class

Custom class that implements the engine factory interface.

To use this algorithm mapping feature, specify a custom algorithm class in the Algorithm factory engine class field for digital signature, data encryption, digest value calculation, and key encryption. The algorithm factory engine provides a plug-in point for service providers to provide their implementation for digest value calculation, digital signature, key encryption, and data encryption that is based on a specified algorithm uniform resource identifier (URI). By clicking Algorithm URI under Additional properties, we can specify the algorithm URI and its usage type. This product supports the following algorithm types:

Message digest

Algorithm URI used for digest value calculation.

Signature

Algorithm URI used for digital signatures including both signing and signature verification.

Data encryption

Algorithm URI used for both encrypting and decrypting data.

Key encryption

Algorithm URI used for both encrypting and decrypting the encryption key.

If the URI is used for multiple usage types, then define a mapping of the URI to each usage type. The actual implementation of the algorithm is provided by the custom class that implements the engine factory interface.

See, refer to the information center documentation on how to implement a factory class.
