Norbert, Holger,

I think an SSL Plugin for OS X based on the OpenSSL code for (L|U)nix is *very* important. 

Could you please share it, just for testing, please, please ?

Thx,

Sven

He just compiled the Mac plugin using the unix openssl sources. I just copied that in the VM folder and then I could do the same on my Mac. I tried to send a push message via apples push server using:

I have the certificates in a database and writing a file everytime I want to send something is not that good. Especially not if there are concurrent requests for sending messages.

There is no code for specifying a CA chain. So this is resolved system wide and that means you need to install every CA for your certificate in the system.
