Topic: boost:: iostreams filter, CRC

Before to write most, wanted to ask at ALL. Anybody casually did not meet ready implementation Output of the filter for count CRC (CRC32 or MD5) which can be thrust in  before device and then to take away from it result. Like such bicycle precisely should exist?

Here it turns out two tasks: 1) Count CRC it is valid "bicycle" (examples - beginning from boost: http://www.boost.org/doc/libs/1_60_0/libs/crc and including other variants: https://www.codeproject.com/articles/16 … for-a-file http://stackoverflow.com/questions/3029 … mentation) 2) Support " before device" is the task demanding more creative approach (I am afraid that here it is necessary to write something the even if to apply together with Boost. Iostreams).  here it: http://www.boost.org/doc/libs/1_55_0/li … c/zlib.cpp (I do not know, how much it in a subject)

So I just about the filter for boost:: iostreams also asked, there difficult is absolute anything, simply laziness to write the code for such it would be seemed a bicycle, but already wrote.
