Please note that while ToByteArrayUnsigned accounts for the possible
leading zero, it will not give the full 32 bytes in the case where the
field element has a small value relative to the field characteristic. So
please do use X9IntegerConverter or you will get incorrect (short)
output randomly for ~%1 of points.
Better yet, just use ECPoint.GetEncoded() if that is applicable.

Hi Chris,
Wouldn't the ToByteArrayUnsigned() method of the BigInteger class be
helpful in your case?
Cheers,
