HsOpenSSL now has rudimentary support for writing SSL servers[5] (clients coming soon). In terms of blocking IO, this /should/ work the way you would hope (i.e. like a Haskell function w.r.t. forkIO).

Coincidentally, night before last I downloaded the openssl source and started trying to think about an SSL library. The thing is, I have always wished for an SSL library that doesn't do I/O, but just transforms data and leaves the I/O to you. I guess that's going to be a good deal more complicated, and in many cases not worth it at all - so there would need to be an SSLIO layer above it - but clinging to some vague reactive-object ideals I imagine that this `pure' SSL core could fit into some kinds of dispatching frameworks where the usual thing would be awkward. Anyway, I'll write again in a few years if I get around to doing anything about it. Donn Cave, donn@avvanta.com
