Hi all!

Not so long ago I was looking for a solution to Base64 encoding/decoding.

In this page -  
http://www.boost.org/doc/libs/1_46_1/libs/serialization/doc/dataflow.html  
- I found example of such solution, with 'base64_from_binary' and  
'transform_width' iteartors. But it is just a "blank", not ready-to-use  
solution.

I created solution. But I definitely know many developers looking for a  
simple, ready-to-use, header-only and 'real C++' solution for Base64. So I  
want to offer you such solution.

Some examples:

int main() {
     std::string my_text = "My text for encoding!";
     std::string encoded_text = boost::base64().encode( my_text );
     std::string my_text_again = boost::base64().decode< std::string >(  
encoded );
}

For binary data:

int main() {
     typedef std::vector< unsigned char > binary_string;

     binary_string my_bin = list_of( 0xFF )( 0xAA )( 0x01 );
     std::string encoded_bin = boost::base64().encode( my_bin );
     binary_string my_bin_again = boost::base64().decode< binary_string >(  
encoded );
}

For streams:

int main() {
     boost::filesystem::ifstream my_jpeg( "/some/path/to/my/image" );
     // fstream checking omitted...

     std::string encoded_jpeg = boost::base64().encode( my_jpeg );

     boost::filesystem::ofstream my_jpeg_again(  
"/some/path/to/decoded/image" );
     // fstream checking omitted...

     boost::base64().decode( encoded_jpeg, my_jpeg_again );
}

This is first variant. IMHO such solution will be useful for Boost users.

What you think about it?
