Asn1BitString
Creates an ASN.1 BIT STRING from the provided bitSet. The transformation to bitCarryingBytes and the calculation of numPaddingBits happens immediately in the constructor. Hence, modifications to the source BitSet have no effect on the resulting Asn1BitString.
BEWARE: a bitset (as BitSet implements it) is, by definition, only as long as the highest bit set! Hence, trailing zeroes are ALWAYS stripped. If you require tailing zeroes, the easiest quick-and-dirty hack to accomplish this in general is as follows:
set the last bit you require as tailing zero to one
call this constructor
flip the previously set bit back (this will be the lowest bit set in last byte of bitCarryingBytes).
Parameters
the source BitSet, which is discarded after bitCarryingBytes and numPaddingBits have been calculated
Throws
if source does not fulfill the ASN.1 BIT STRING requirements
Constructs an ASN.1 BIT STRING with source used for bitCarryingBytes and zero padding bits
Throws
if source does not fulfill the ASN.1 BIT STRING requirements
