the best way is to

a) make an encrypted stream_buf
b) use this to make an encrypted stream - very easy
c) use your encripted stream with the serialization library just like you do with any other stream

Remember that the archive class just maps types to the underlying stream - any stream will do.

Also you could make a new stream with the boost iostreams library.  This would allow you to make an encrypted and compressed stream with no additional labor.
