The standard Java class java.math.BigInteger is ideal for implementing
crypto algorithms based on modular arithmetic. Since it is not export
controlled in the form of PC/Mac/Unix etc. software, it shouldn't be export
controlled on a smart ring either. (Note: I haven't verified that it is
included in the ring's Java subset.)
