I’ve just released a bit of work that I had been working on for a while. SqueakSSL is a plugin based interface to the native SSL/TLS facilities on your platform. On Windows, it uses the SChannel SSPI and on Unix it uses the OpenSSL implementation. The Mac’s still out there but I’m hoping that the OpenSSL version will work there too.
