Method Detail

setPRF

public void setPRF(PKCS11Algorithm prf)
            throws java.lang.IllegalArgumentException

Set the underlying pseudo-random function from a PKCS11Algorithm enum value.

Throws:

java.lang.IllegalArgumentException

setPRF

public void setPRF(DigestAlgorithm prf)
            throws java.lang.IllegalArgumentException

Set the underlying pseudo-random function from a DigestAlgorithm (HMACAlgorithm or CMACAlgorithm) instance.

Throws:

java.lang.IllegalArgumentException

setPRF

public void setPRF(long prf)

Set the underlying pseudo-random function from a PKCS#11 constant; see org.mozilla.jss.pkcs11.PKCS11Constants for permitted values.

setPRFKey

public void setPRFKey(javax.crypto.SecretKey key)
               throws java.security.InvalidKeyException

Set the base key used with the underlying PRF. Must be importable to a JSS SymmetricKey or SecretKeyFacade.

Throws:

java.security.InvalidKeyException

setDerivedKeyAlgorithm

public void setDerivedKeyAlgorithm(PKCS11Algorithm algo)
                            throws java.lang.IllegalArgumentException

Set the algorithm for the derived key from a PKCS11Algorithm enum value.

Throws:

java.lang.IllegalArgumentException

setDerivedKeyAlgorithm

public void setDerivedKeyAlgorithm(long algo)
                            throws java.lang.IllegalArgumentException

Sets the algorithm for the derived key from a PKCS#11 value; see org.mozilla.jss.pkcs11.PKCS11Constants for constant values.

Throws:

java.lang.IllegalArgumentException

setKeySize

public void setKeySize(int keySize)

Set the size of the derived key. If zero, will attempt to use the derived key algorithm's default key size.

setParameters

public void setParameters(KBKDFDataParameter[] params)
                   throws java.lang.IllegalArgumentException

Set parameters for key derivation. This overwrites all existing parameters. Note that params cannot be NULL.

Throws:

java.lang.IllegalArgumentException

addParameter

public void addParameter(KBKDFDataParameter param)
                  throws java.lang.IllegalArgumentException

Appends (to the end) a new data parameter.

Throws:

java.lang.IllegalArgumentException

setAdditionalDerivedKeys

public void setAdditionalDerivedKeys(KBKDFDerivedKey[] additional_keys)
                              throws java.lang.IllegalArgumentException

Set an array of additional derived keys.

Throws:

java.lang.IllegalArgumentException

addAdditionalDerivedKey

public void addAdditionalDerivedKey(KBKDFDerivedKey derived_key)
                             throws java.lang.IllegalArgumentException

Append (to the end) a new derived key.

Throws:

java.lang.IllegalArgumentException

acquireNativeResources

protected void acquireNativeResources()
                               throws java.lang.Exception

Description copied from class: NativeEnclosure

Allocate native resources, setting mPointer and mPointerSize as appropriate.

Specified by:

acquireNativeResources in class NativeEnclosure

Throws:

java.lang.Exception

releaseNativeResources

protected void releaseNativeResources()
                               throws java.lang.Exception

Description copied from class: NativeEnclosure

Called to deallocate native resources; note that mPointer.close() is called afterwards. If mPointer.close() should be a no-op, extend from StaticVoidRef and do any required cleanup here.

Specified by:

releaseNativeResources in class NativeEnclosure

Throws:

java.lang.Exception

acquireNativeResourcesInternal

protected abstract void acquireNativeResourcesInternal()
                                                throws java.lang.Exception

Throws:

java.lang.Exception

releaseNativeResourcesInternal

protected abstract void releaseNativeResourcesInternal()
                                                throws java.lang.Exception

Throws:

java.lang.Exception

validateParameters

protected abstract void validateParameters()
                                    throws java.lang.IllegalArgumentException

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.

Throws:

java.lang.IllegalArgumentException
