/Length integer
(Optional) The bit length of the encryption key. It shall be a multiple of 8 in the range of 40 to 128. Security handlers may define their own use of the Length entry and should use it to define the bit length of the encryption key. Standard security handler expresses the length in multiples of 8 (16 means 128) and public-key security handler expresses it as is (128 means 128).
