        Base constructor.
        Parameters:
        password - password to use as the seed of the PBE key generator.
        salt - salt to use in the generator,
        iterationCount - iteration count to use in the generator.
        keySize - size of the key to be generated (in bits).
        prf - identifier and parameters for the PRF algorithm to use.

      • isDefaultPrf

        public boolean isDefaultPrf()
        Return true if this spec is for the default PRF (HmacSHA1), false otherwise.
        Returns:
        true if this spec uses the default PRF, false otherwise.

      • getPrf

        public AlgorithmIdentifier getPrf()
        Return an AlgorithmIdentifier representing the PRF.
        Returns:
        the PRF's AlgorithmIdentifier.
