* Find OpenSSL version
* Create and update various config files
* Update logic to use new version constraints
* SSL_OPTIONS_HASHES_NEW and SSL_OPTIONS_HASHES_MEDIUM were just being used for testing, and maintaining them is becoming untenable, so remove them.
* if we don't know the openssl version, we can't turn off session tickets
* add unit test for _get_openssl_version
* add unit tests
* placate lint
* Fix docs and tests and clean up code
* use python correctly
* update changelog
* Lint
* make comment a comment
* Follow Mozilla recs for Nginx ssl_protocols, ssl_ciphers, and ssl_prefer_server_ciphers
* Add tests and fix if statement
* Update CHANGELOG.md
Co-Authored-By: Brad Warren <bmw@users.noreply.github.com>
* Test that the hashes of all of the current configuration files are in ALL_SSL_OPTIONS_HASHES
* Remove conditioning on OpenSSL version, since Nginx behaves cleanly if its linked OpenSSL doesn't support TLS1.3
* Turn off session tickets for versions of Nginx that support it
In line with Mozilla's security recommendations.
* Changelog.
* Set version before installing config files
* lint: remove unused import
* windows testfix
* another windows testfix?
* Testing path of updating src file with old nginx
* Fix windows, and make config update tests fail if update doesn't happen
