```
public void destroy()
```
    Destroy this key, clearing the key material it holds.
    The values are held as BigIntegers, which are immutable and so cannot be zeroized in place - destruction drops the internal references so the values become unreachable (cleared on garbage collection). The (public) modulus is retained, so hashCode() and getModulus() remain stable across destruction. The underlying RSAKeyParameters object is destroyed as well, so keys sharing it are invalidated too. After destruction isDestroyed() returns true, getEncoded() and getPrivateExponent() throw IllegalStateException, and the key can no longer be serialized.
