A CipherInputStream is composed of an InputStream and a Cipher so that
read() methods return data that are read in from the underlying InputStream but
have been additionally processed by the Cipher.
A CipherOutputStream is composed of an OutputStream and a Cipher so that
write() methods first process the data before writing them out to the
underlying OutputStream.

in order to hold the result of the next update or doFinal operation,
given the input length inputLen (in bytes).
