Method Detail

• withParameterSpec

  public KTSParameterSpec.Builder withParameterSpec​(java.security.spec.AlgorithmParameterSpec parameterSpec)

  Set the algorithm parameter spec to be used with the wrapper.

  Parameters:

  parameterSpec - the algorithm parameter spec to be used in wrapping/unwrapping.

  Returns:

  the current Builder instance.

• withKdfAlgorithm

  public KTSParameterSpec.Builder withKdfAlgorithm​(AlgorithmIdentifier kdfAlgorithm)

  Set the KDF algorithm and digest algorithm for wrap key generation.

  Parameters:

  kdfAlgorithm - the KDF algorithm to apply.

  Returns:

  the current Builder instance.

• build

  public KTSParameterSpec build()

  Build the new parameter spec.

  Returns:

  a new parameter spec configured according to the builder state.
