      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:
      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:
