Class DG14File

java.lang.Object

org.jmrtd.lds.DataGroup

org.jmrtd.lds.DG14File

All Implemented Interfaces:

java.io.Serializable, LDSElement, LDSFile

public class DG14File
extends DataGroup

Data Group 14 stores a set of SecurityInfos for EAC and PACE, see BSI EAC 1.11 and ICAO TR-SAC-1.01. To us the interesting bits are: the map of public keys (EC or DH), 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(java.util.Collection<SecurityInfo> securityInfos)

Constructs a new DG14 file from the provided data.

Parameters:

securityInfos - a list of security infos

DG14File

public DG14File(java.io.InputStream inputStream)
         throws java.io.IOException

Constructs a new DG14 file from the data in an input stream.

Parameters:

inputStream - the input stream to parse the data from

Throws:

java.io.IOException - on error reading from input stream

Method Detail

readContent

protected void readContent(java.io.InputStream inputStream)
                    throws java.io.IOException

Description copied from class: DataGroup

Reads the contents of the data group from an input stream. Client code implementing this method should only read the contents from the input stream, not the tag or length of the data group.

Specified by:

readContent in class DataGroup

Parameters:

inputStream - the input stream to read from

Throws:

java.io.IOException - on error reading from input stream

writeContent

protected void writeContent(java.io.OutputStream outputStream)
                     throws java.io.IOException

Description copied from class: DataGroup

Writes the contents of the data group to an output stream. Client code implementing this method should only write the contents to the output stream, not the tag or length of the data group.

Specified by:

writeContent in class DataGroup

Parameters:

outputStream - the output stream to write to

Throws:

java.io.IOException - on error writing to output stream

getCVCAFileIds

public java.util.List<java.lang.Short> getCVCAFileIds()

Gets the list of file identifier references to efCVCA files, possibly empty.

Returns:

the list of file identifier references

getCVCAShortFileId

public byte getCVCAShortFileId(int fileId)

Gets a corresponding short file ID.

Parameters:

fileId - the file ID

Returns:

an SFI for the given file ID, -1 if not present

getChipAuthenticationInfos

public java.util.Map<java.math.BigInteger,java.lang.String> getChipAuthenticationInfos()

Gets the mapping of key identifiers to EAC protocol identifiers contained in this file. The key identifier may be -1 if there is only one protocol identifier.

Returns:

the mapping of key identifiers to EAC protocol identifiers

getActiveAuthenticationInfos

public java.util.List<ActiveAuthenticationInfo> getActiveAuthenticationInfos()

getChipAuthenticationPublicKeyInfos

public java.util.Map<java.math.BigInteger,java.security.PublicKey> getChipAuthenticationPublicKeyInfos()

Gets the mapping of key identifiers to public keys. The key identifier may be -1 if there is only one key.

Returns:

the mapping of key identifiers to public keys

getSecurityInfos

public java.util.Collection<SecurityInfo> getSecurityInfos()

Gets the security infos as an unordered collection.

Returns:

security infos

toString

public java.lang.String toString()

Description copied from class: DataGroup

Gets a textual representation of this file.

Overrides:

toString in class DataGroup

Returns:

a textual representation of this file

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

getEncoded

public byte[] getEncoded()

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

Specified by:

getEncoded in interface LDSElement

Returns:

a byte array containing the file
