Interface AlgorithmsProvider

All Known Implementing Classes:

DefaultAlgorithmsProvider

public interface AlgorithmsProvider

Interface for providers of the algorithms used in the signature generation. An instance of a class implementing this interface is supplied to the signer which will query the instance whenever he needs an algorithm information (when generating ds:Reference elements, for instance).

The methods on this classes must not return null.

This allows the customization of the different algotihms used in the signature. A default implementation is provided.
