Hi, PEP 543, the new TLS api for Python, was published several years ago as a way to a new library unencumbered by the legacy issues around the current ssl library. In the meantime, no actual implementation has appeared. The closest appears to be https://github.com/Synss/python-mbedtls/tree/0.13.0 or https://github.com/python-hyper/pep543 both of which haven't seen much development in years not to mention that neither one has been accepted into the stdlib. The current ssl library could use some improvements to make it easier to use and to expose some more of openssl's functionality (e.g. https://github.com/python/cpython/pull/2449) but it appears that changes have been shelved in favor of PEP 543. Is there any hope for further development on ssl? Is PEP 543 abandoned? Nimish
