Method Detail

getSignerCertRef

public static String[] getSignerCertRef(X509Certificate cert)
                                 throws InvalidNameException

Return the Signer Identifier and the Certificate Reference based on the the given X.509. Signer Identifier is C + CN Certificate Reference is the serial number of the X509Certificate. It will be encoded as hexstring

Parameters:

cert - X509 certificate to get the signer information from

Returns:

String array that contains the signerIdentifier at index 0 and CertRef at index 1

Throws:

InvalidNameException - if a syntax violation is detected.

encodeDate

public static byte[] encodeDate(String dateString)
                         throws ParseException

Parameters:

dateString - Date as String formated as yyyy-MM-dd

Returns:

date encoded in 3 bytes

Throws:

ParseException - if dateString is not in format yyyy-MM-dd

encodeDate

public static byte[] encodeDate(LocalDate localDate)

Encode a LocalDate as described in ICAO Doc9303 Part 13 in three bytes

Parameters:

localDate - Date

Returns:

date encoded in 3 bytes

encodeDateTime

public static byte[] encodeDateTime(LocalDateTime localDatetime)

Encode a LocalDate as described in as described in ICAO TR "Datastructure for Barcode" in six bytes.

Parameters:

localDatetime - LocalDateTime to encode

Returns:

local date time encoded in 6 bytes

encodeMaskedDate

public static byte[] encodeMaskedDate(String dateString)

Encodes a date string with unknown date parts as described in ICAO TR "Datastructure for Barcode". Unknown parts of the date string shall be filled with an 'x', e.g. 19xx-10-xx

Parameters:

dateString - date as String formated as yyyy-MM-dd where unknown parts could be replaced by an x

Returns:

masked date encoded in 4 bytes
