-/**
- * A CipherOutputStream is composed of an OutputStream and a cipher so that write() methods process
- * the written data with the cipher, and the output of the cipher is in turn written to the
- * underlying OutputStream. The cipher must be fully initialized before being used by a
- * CipherInputStream.
- * <p>
- * For example, if the cipher is initialized for encryption, the CipherOutputStream will encrypt the
- * data before writing the encrypted data to the underlying stream.
- * </p><p>
- * This is a reimplementation of {@link javax.crypto.CipherOutputStream} that is safe for use with
- * AEAD block ciphers, and does not silently catch {@link BadPaddingException} and
- * {@link IllegalBlockSizeException} errors. Any errors that occur during {@link Cipher#doFinal()
- * finalisation} are rethrown wrapped in an {@link InvalidCipherTextIOException}.
- * </p>
