-### A word about Security
-
-Handling outgoing requests can be a security nightmare. This crate does not control the client for the outgoing requests, as it needs to be supplied to the proxy call. The following chapters may give you an overview on how you can secure your client using the `hyper-trust-dns` crate.
-
-> You can see them being used in the example.
-
-#### HTTPS
-
-You should use a secure transport in order to know who you are talking to and so you can trust the connection. By default `hyper-trust-dns` enables the feature flag `https-only` which will panic if you supply a transport scheme which isn't `https`. It is a healthy default as it's not only you needing to trust the source but also everyone else seeing the content on unsecure connections.
-
-> ATTENTION: if you are running on a host with added certificates in your cert store, make sure to audit them in a interval, so neither old certificates nor malicious certificates are considered as valid by your client.
-
-#### TLS 1.2
-
-By default `tls 1.2` is disabled in favor of `tls 1.3`, because many parts of `tls 1.2` can be considered as attach friendly. As not yet all services support it `tls 1.2` can be enabled via the `rustls-tls-12` feature.
-
-> ATTENTION: make sure to audit the services you connect to on an interval
-
-#### DNSSEC
-
-As dns queries and entries aren't "trustworthy" by default from a security standpoint. `DNSSEC` adds a new cryptographic layer for verification. To enable it use the `dnssec-ring` feature.
-
-#### HTTP/2
-
-By default only rustls `http1` feature is enabled for dns queries. While `http/3` might be just around the corner. `http/2` support can be enabled using the `rustls-http2` feature.
-
-#### DoT & DoH
-
-DoT and DoH provide you with a secure transport between you and your dns.
-
-By default none of them are enabled. If you would like to enabled them, you can do so using the features `doh` and `dot`.
-
-Recommendations:
- - If you need to monitor network activities in relation to accessed ports, use dot with the `dns-over-rustls` feature flag
- - If you are out in the wild and have no need to monitor based on ports, doh with the `dns-over-https-rustls` feature flag as it will blend in with other `https` traffic
-
-It is highly recommended to use one of them.
-
-> Currently only includes dns queries as `esni` or `ech` is still in draft by the `ietf`
