Code Review: 7160837 DigestOutputStream does not turn off digest calculation when "close()" is called

[Anthony Scarpino]

Hi,

Below is the link to code changes for:  DigestOutputStream does not turn 
off digest calculation when "close()" is called.

The more significant change is to the Cipher streams to prevent extra 
doFinal() calls.
