have you tried to use these functions from python as well?

[rcarpa]

Good point. I actually didn't. For some reason I assumed it's as simple as just exposing these bindings and that's all. Is it more tricky than that ?

[arvidn]

type conversions are performed at run-time in python, not compile-time. So it may still fail when running it in python

Just tried the functions from python. Both work as expected.

• ssl_listen_port returns an integer (0 if not listening on the ssl socket)
• set_ssl_certificate_buffer works correctly when passing strings or bytes with pem-encoded content. I successfully transferred files between two instances of a (patched) Deluge using an encrypted connection.

To be noted that set_ssl_certificate_buffer accepts (without any errors) strings containing invalid data. It only results in silent failures to establish the SSL connection. However, this is not something specific to the python bindings.
