Class Summary

Class	Description
BCDUtil	The BCDUtil class contains common BCD(binary coded decimal) related utility functions.
BigNumber	The BigNumber class encapsulates an unsigned number whose value is represented in internal hexadecimal format using an implementation specific maximum number of bytes.
ParityBit	The ParityBit class is a utility to assist with DES key parity bit generation.

Package javacardx.framework.math Description

Extension package that contains common utility functions for BCD math and parity computations. If implemented, the implementation must also include the other sub-packages of javacardx.framework - util, and tlv.

The javacardx.framework.math package contains the BCDUtil class, the BigNumber class, the ParityBit class. The BCDUtil class provides methods for converting array data from hexadecimal format to BCD and vice versa. The BigNumber class supports a stored value paradigm for a storing large unsigned value and performing arithmetic operations on it. The ParityBit class is useful for computing the parity bits on a derived DES key.
