Constructor Detail

AbstractEncryptionAlgorithmsLookupStrategy

protected AbstractEncryptionAlgorithmsLookupStrategy(@Nullable
                                                     AlgorithmRegistry registry)

Constructor.

Parameters:

registry - the algorithm registry to used when resolving algorithm URIs. Defaults to the registry resolved via AlgorithmSupport.getGlobalAlgorithmRegistry()

Method Detail

getAlgorithmRuntimeSupportedPredicate

@Nonnull
protected Predicate<String> getAlgorithmRuntimeSupportedPredicate()

Get a predicate which evaluates whether a cryptographic algorithm is supported by the runtime environment.

Returns:

the predicate

getAlgorithmRegistry

protected AlgorithmRegistry getAlgorithmRegistry()

Get the algorithm registry.

Returns:

the algorithm registry

findAlgorithmIntersection

@Nonnull
protected List<String> findAlgorithmIntersection(@Nonnull
                                                 List<String> providerAlgorithms,
                                                 @Nonnull
                                                 List<String> configAlgorithms)

Return a new list of algorithms that represents the set intersection of the two input algorithm lists. The original order of algorithms from the configAlgorithms list is preserved.

Parameters:

providerAlgorithms - the set of algorithms specified by the OpenID Provider

configAlgorithms - the set of algorithms specified by the IdP's configuration

Returns:

the intersection of both lists
