OpenSSL Transport for asyncio
The transport has two main advantages compared to the original:
The TLS handshake can be deferred by passing
use_starttls=Trueand later calling the
This is useful for protocols with a STARTTLS feature.
A coroutine can be called during the TLS handshake; this can be used to defer the certificate check to a later point, allowing e.g. to get user feedback before the
This allows to ask users for certificate trust without the application layer protocol interfering or starting to communicate with the unverified peer.
Use this module at your own risk. It has lower test coverage than I’d like it to have; it has been exported from aioxmpp on request, where it undergoes implicit testing. If you find bugs, please report them. If possible, add regression tests while you’re at it.
If you find security-critical bugs, please follow the procedure announced in the aioxmpp readme.`
Official documentation can be built with sphinx and is available online on our servers.
