      • PKCS12ParametersGenerator

        public PKCS12ParametersGenerator​(Digest digest)
        Construct a PKCS 12 Parameters generator. This constructor will accept any digest which also implements ExtendedDigest.
        Parameters:
        digest - the digest to be used as the source of derived keys.
        Throws:
        java.lang.IllegalArgumentException - if an unknown digest is passed in.

      • generateDerivedParameters

        public CipherParameters generateDerivedParameters​(int keySize)
        Generate a key parameter derived from the password, salt, and iteration count we are currently initialised with.
        Specified by:
        generateDerivedParameters in class PBEParametersGenerator
        Parameters:
        keySize - the size of the key we want (in bits)
        Returns:
        a KeyParameter object.

      • generateDerivedParameters

        public CipherParameters generateDerivedParameters​(int keySize,
                                                  int ivSize)
        Generate a key with initialisation vector parameter derived from the password, salt, and iteration count we are currently initialised with.
        Specified by:
        generateDerivedParameters in class PBEParametersGenerator
        Parameters:
        keySize - the size of the key we want (in bits)
        ivSize - the size of the iv we want (in bits)
        Returns:
        a ParametersWithIV object.

      • generateDerivedMacParameters

        public CipherParameters generateDerivedMacParameters​(int keySize)
        Generate a key parameter for use with a MAC derived from the password, salt, and iteration count we are currently initialised with.
        Specified by:
        generateDerivedMacParameters in class PBEParametersGenerator
        Parameters:
        keySize - the size of the key we want (in bits)
        Returns:
        a KeyParameter object.
