Thanks for your interest. I don't see anything principally wrong with
your code. You may have noticed the src/stlbench.cpp program, which
does some basic performance comparison between stlencoders and some
other encoding libraries, but not OpenSSL so far. It would be great if
you'd give a try and add OpenSSL support to that! Please send me a
patch if you find the time.
