Field Detail

ECC_SIGNATURE_TYPE_PREFERENCES

static final List<String> ECC_SIGNATURE_TYPE_PREFERENCES

ECC signature types in ascending order of preference (i.e., most preferred 1st)

Method Detail

resolveSignatureFactoriesProposal

static List<String> resolveSignatureFactoriesProposal(Iterable<String> provided,
                                                      Collection<? extends NamedFactory<Signature>> factories)

Parameters:

provided - The provided signature key types

factories - The available signature factories

Returns:

A List of the matching available factories names that are also listed as provided ones - in the same order of preference as they appear in the available listing. May be empty if no provided signature key types, or no available ones or no match found.

                                                         Collection<String> available)

Parameters:

provided - The provided signature key types

available - The available signature factories names

Returns:

A List of the matching available factories names that are also listed as provided ones - in the same order of preference as they appear in the available listing. May be empty if no provided signature key types, or no available ones or no match found.
