[Boost-users] boost.Iostream OpenSSL Filter

I am currently looking at using OpenSSL to write information to an
encrypted file on-the-fly so to speak. I have been researching my
options for doing this, and have come across the Boost.Iostream library,
which promises to be a very elegant solution (The documentation even
suggests that filters can be written to provide encryption/decryption
using OpenSSL). 
It would seem that my best approach would be to use the BIO_f* interface
to encrypt a memory buffer, which could be written by overloading
write(). However the OpenSSL documentation is particularly sparse when
it comes to file/memory encryption and I would appreciate any advice on
how to do this.
Thank you in advance for any help proffered.
