Method Detail

getPublicExponent

public java.math.BigInteger getPublicExponent()

getP

public java.math.BigInteger getP()

getQ

public java.math.BigInteger getQ()

getDP

public java.math.BigInteger getDP()

getDQ

public java.math.BigInteger getDQ()

getQInv

public java.math.BigInteger getQInv()

destroy

public void destroy()

Destroy this object, dropping its references to the CRT factors and exponents along with the inherited private exponent. The (public) modulus and public exponent are retained.

As BigInteger is immutable the values cannot be zeroized in place; destruction drops the internal references so the values become unreachable (cleared on garbage collection). After destruction the secret-bearing accessors throw IllegalStateException.

Specified by:

destroy in interface javax.security.auth.Destroyable
