Method Detail

setInitialValue

public void setInitialValue(byte[] iv)
                     throws java.lang.IllegalArgumentException

Throws:

java.lang.IllegalArgumentException

zeroInitialValue

public void zeroInitialValue()

Zero out the copiend contents of the initial value. Call this method when the contents of the initial value are sensitive and they're done being used. Note that this isn't called during close() as a given KBKDFParameterSpec instance may be reused, updating relevant parameters between calls.

validateParameters

protected void validateParameters()
                           throws java.lang.IllegalArgumentException

Description copied from class: KBKDFParameterSpec

Validate all class members prior to acquiring native resources. This is implemented by the derived KBKDF modes in an effort to give useful exceptions before derivation, instead of vague errors during derivation.

Specified by:

validateParameters in class KBKDFParameterSpec

Throws:

java.lang.IllegalArgumentException

acquireNativeResourcesInternal

protected void acquireNativeResourcesInternal()
                                       throws java.lang.Exception

Specified by:

acquireNativeResourcesInternal in class KBKDFParameterSpec

Throws:

java.lang.Exception

releaseNativeResourcesInternal

protected void releaseNativeResourcesInternal()
                                       throws java.lang.Exception

Specified by:

releaseNativeResourcesInternal in class KBKDFParameterSpec

Throws:

java.lang.Exception
