The certificate validation introduced in 2.0.5 doesn't work where the cert requires a password. In theory the fix is as simple as supplying the password as a second argument but in my brief tests that didn't work either.
The symptoms are severe: OpenSSL prompts for a password, which in server context locks the whole process irretrievably.
I will investigate further but this isn't really my area.
Validate certificates with a password. Fixes #92.
