                              ECDomainParameters parameters)

Method Detail

getD

public java.math.BigInteger getD()

destroy

public void destroy()

Destroy this object, dropping its reference to the private value.

As BigInteger is immutable the private value cannot be zeroized in place; destruction drops the internal reference so the value becomes unreachable (cleared on garbage collection). After destruction getD() throws IllegalStateException.
