public class DG14File
extends DataGroup

Data Group 14 stores a set of SecurityInfos for Extended Access Control, see EAC 1.11 spec. To us the interesting bits are: the map of public (EC or DH) keys, the map of protocol identifiers which should match the key's map (not checked here!), and the file identifier of the efCVCA file.

Constructor Detail

DG14File

public DG14File(List<SecurityInfo> securityInfos)

Constructs a new DG14 file from the provided data.

Parameters:

securityInfos - a list of security infos

DG14File

public DG14File(InputStream in)

Constructs a new DG14 file from the data in in.

Parameters:

in - the input stream to parse the data from

DG14File

public DG14File(Map<Integer,PublicKey> publicKeys,
                Map<Integer,DERObjectIdentifier> chipInfoMap,
                List<Integer> cvcaFileIdList,
                Map<Integer,Integer> cvcaShortFileIdMap)

Constructs a new DG14 file from the provided data.

Parameters:

publicKeys - the map of (EC or DH) public keys indexed by key identifiers. If only one key, the index can be -1.

chipInfoMap - the map of protocol identifiers for EAC indexed by key identifiers. If only one protocol identifier, the index can be -1.

cvcaFileIdList - the list of file identifiers of the efCVCA file(s)

cvcaShortFileIdMap - a mapping of file identifiers (see above) to short file identifiers (can be empty)

Method Detail

getEncoded

public byte[] getEncoded()

Description copied from class: PassportFile

Gets the contents of this file as byte array, includes the ICAO tag and length.

Specified by:

getEncoded in class DataGroup
