encodeKeyParams

protected abstract ConstructedTLV encodeKeyParams()

encodeSpecParams

protected void encodeSpecParams(Sequence cdata)

Description copied from class: SmartCardHSMKeySpec

Encode key specification for asymmetric keys Overwritten in derived classes

Overrides:

encodeSpecParams in class SmartCardHSMKeySpec

Parameters:

cdata - the TLV structure to which objects are added

unsignedBigIntegerToByteArray

protected static byte[] unsignedBigIntegerToByteArray(java.math.BigInteger bi,
                                                      int size)

Convert unsigned big integer into byte array, stripping of a leading 00 byte This conversion is required, because the Java BigInteger is a signed value, whereas the byte arrays containing key components are unsigned by default

Parameters:

bi - BigInteger value to be converted

size - Number of bits

Returns:

Byte array containing unsigned integer value
