In case there is a problem with sending zipped files i just list my
code here(with no tests or docs,just hpp):
#ifndef BOOST_CHECKSUM_HPP
#define BOOST_CHECKSUM_HPP

#include <boost/cstdint.hpp>
#include <vector>

namespace boost {
        typedef boost::uint8_t byte;
        class checksum {

                checksum(const checksum&);
                checksum(const std::vector<byte>&);
                void process();
                void put_data(const std::vector<byte>&);

                bool proceeded() const;
        private:

        };//boost::checksum
        inline checksum::checksum() : sum(0), done(false)
        {
        }
        inline checksum::checksum(const boost::checksum &cs) 
        {
                sum=cs.sum;
                done=cs.done;
                in_data=cs.in_data;
        }
        inline checksum::checksum(const std::vector<byte> &_in_data) : sum(0), done(false), in_data(_in_data)
        {
        }
        inline void checksum::process()
        {
                if (!done) {
                        uint8_t temp_sum=0;
                        for (std::vector<byte>::const_iterator it=in_data.begin();it<in_data.end();it++)

        }
