How can I set ssl key passwd?

[barabaspeter]

I merged my key and cert pem files into one file for apple push notification. I want to set the password for the key, but i cannot find setopt_sslkeypasswd.
Is is missing or is there any other way to do this?

I think I miss this one. I think I add it today or tomorrow. Or you can make PR.
I think it just one line like this
