Constructor Detail

ReadBinaryAPDUSender

public ReadBinaryAPDUSender(net.sf.scuba.smartcards.CardService service)

Creates an APDU sender.

Parameters:

service - the card service for tranceiving APDUs

Method Detail

sendSelectApplet

public void sendSelectApplet(net.sf.scuba.smartcards.APDUWrapper wrapper,
                             byte[] aid)
                      throws net.sf.scuba.smartcards.CardServiceException

Sends a SELECT APPLET command to the card.

Specified by:

sendSelectApplet in interface APDULevelReadBinaryCapable

Parameters:

wrapper - the secure messaging wrapper to use

aid - the applet to select

Throws:

net.sf.scuba.smartcards.CardServiceException - on tranceive error

sendSelectFile

public void sendSelectFile(net.sf.scuba.smartcards.APDUWrapper wrapper,
                           short fid)
                    throws net.sf.scuba.smartcards.CardServiceException

Sends a SELECT FILE command to the passport. Secure messaging will be applied to the command and response apdu.

Specified by:

sendSelectFile in interface APDULevelReadBinaryCapable

Parameters:

wrapper - the secure messaging wrapper to use

fid - the file to select

Throws:

net.sf.scuba.smartcards.CardServiceException - on tranceive error

sendReadBinary

public byte[] sendReadBinary(net.sf.scuba.smartcards.APDUWrapper wrapper,
                             int sfi,
                             int offset,
                             int le,
                             boolean isSFIEnabled,
                             boolean isTLVEncodedOffsetNeeded)
                      throws net.sf.scuba.smartcards.CardServiceException

Sends a READ BINARY command to the passport. Secure messaging will be applied to the command and response APDU.

Specified by:

sendReadBinary in interface APDULevelReadBinaryCapable

Parameters:

wrapper - the secure messaging wrapper to use, or null for none

sfi - the short file identifier byte of the file to read as an int value (between 0 and 255) only if isSFIEnabled is true, if not any value)

offset - offset into the file (either a value between 0 and 255 if isSFIEnabled is true, of a value between 0 and 65535 if not)

le - the expected length of the file to read

isSFIEnabled - a boolean indicating whether short file identifiers are used

isTLVEncodedOffsetNeeded - a boolean indicating whether it should be a long (INS == 0xB1) read

Returns:

a byte array of length at most le with (the specified part of) the contents of the currently selected file

Throws:

net.sf.scuba.smartcards.CardServiceException - if the command was not successful
