Thanks to Ben Reeves for the report and Tomas Pomin for the solution.

Fixed all cases of unsafe BigInteger <-> byte[] conversion.
The BigInteger class we're using supports negative integers and
encodes them with a sign bit. Since in our application we are dealing
with unsigned integers only, we need to disable this functionality by
creating two wrapper functions toByteArrayUnsigned and
fromByteArrayUnsigned.
