* Switch to rustls and webpki-roots (#30025)Martin Robinson2023-08-081-16/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change replaces OpenSSL with rustls and also the manually curated CA certs file with webpki-roots (effectively the same thing, but as a crate). Generally speaking the design of the network stack is the same. Changes: - Code around certificate overrides needed to be refactored to work with rustls so the various thread-safe list of certificates is refactored into `CertificateErrorOverrideManager` - hyper-rustls takes care of setting ALPN protocols for HTTP requests, so for WebSockets this is moved to the WebSocket code. - The safe set of cypher suites is chosen, which seem to correspond to the "Modern" configuration from [1]. This can be adjusted later. - Instead of passing a string of PEM CA certificates around, an enum is used that includes parsed Certificates (or the default which reads them from webpki-roots). - Code for starting up an SSL server for testing is cleaned up a little, due to the fact that the certificates need to be overriden explicitly now. This is due to the fact that the `webpki` crate is more stringent with self-signed certificates than SSL (CA certificates cannot used as end-entity certificates).
