    • getCipher

      public Cipher getCipher()
      Returns an initialized cipher object for an appropriate default algorithm and parameters. A best-effort attempt will be made to pick a strong cipher algorithm based on the type of key.
      Returns:
      the initialized cipher object.
    • asCryptoKey

      public KeyEncryptionKey asCryptoKey()
      Description copied from interface: EncryptionKey
      Returns the same object as a specific CryptoKey subclass.
      Specified by:
      asCryptoKey in interface EncryptionKey<KeyEncryptionKey>
      Returns:
      the same key as a CryptoKey.
    • getCipher

      public Cipher getCipher(String algorithm, AlgorithmParameterSpec parameterSpec)
      Returns an initialized cipher object for the given algorithm and parameters.
      Parameters:
      algorithm - the cipher algorithm.
      parameterSpec - the parameters to initialise the cipher with.
      Returns:
      the initialized cipher object.
    • getCipher

      public Cipher getCipher(String algorithm, AlgorithmParameters parameters)
      Returns an initialized cipher object for the given algorithm and parameters.
      Parameters:
      algorithm - the cipher algorithm.
      parameters - the parameters to initialise the cipher with.
      Returns:
      the initialized cipher object.
    • getCipher

      public Cipher getCipher(String algorithm)
      Returns an initialized cipher object with default parameters.
      Parameters:
      algorithm - the cipher algorithm.
      Returns:
      the initialized cipher object.
