Re: [Boost-users] [serialization] deserializing chunk by chunk

Hi,

I have an encrypted archive. I can decrypt the file chunk by chunk. I wonder if there is a way to deserialize each chunk on the fly. The main purpose is to reduce the memory footprint of the application since the archive can be a few hundred mega bytes. The problem as I mentioned is the file is encrypted and it has to be decrypted first in the memory and then deserialized.

Have you looked at boost iostreams library? You can create a filter to provide a decrypted stream which is then used by the input archive. See: http://www.boost.org/doc/libs/1_52_0/libs/iostreams/doc/index.html Jeff
