  • Method Details

    • getBlockCipherSpec

      public Spec<org.bouncycastle.crypto.BufferedBlockCipher> getBlockCipherSpec()
      Returns:
      Block cipher specification.

    • setBlockCipherSpec

      public void setBlockCipherSpec(Spec<org.bouncycastle.crypto.BufferedBlockCipher> blockCipherSpec)
      Sets the block cipher specification.
      Parameters:

    • newCipher

      protected BufferedBlockCipherAdapter newCipher(CiphertextHeader header, boolean mode)
      Description copied from class: AbstractBlockCipherBean
      Creates a new cipher adapter instance suitable for the block cipher used by this class.
      Specified by:
      newCipher in class AbstractBlockCipherBean
      Parameters:
      header - Ciphertext header.
      mode - True for encryption; false for decryption.
      Returns:
      Block cipher adapter that wraps an initialized block cipher that is ready for use in the given mode.
