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. |
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.
