  - destroy
```
public void destroy()
```
    Destroy this object, dropping its reference to the exponent. The (public) modulus is retained.
    As BigInteger is immutable the exponent cannot be zeroized in place; destruction drops the internal reference so the value becomes unreachable (cleared on garbage collection). After destruction getExponent() throws IllegalStateException.
    This type also backs RSA public keys; destroying one of those drops the (non-secret) public exponent, which is harmless but renders the key unusable.
