Constructor Detail

DSAPrivateKeyParameters

public DSAPrivateKeyParameters(java.math.BigInteger x,
                               DSAParameters params)

Method Detail

getX

public java.math.BigInteger getX()

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). The (public) domain parameters are retained. After destruction getX() throws IllegalStateException.
