`async_native_tls` / `native_tls` error when running `hyper-server` example

[Myriade-Medieval]

Trying to implement https for my own smol+hyper powered server, I turned to the hyper-server example for implementation.

Though, when running it, it crashes instantaneously:

$ cargo run --example hyper-server
    Finished `dev` profile [unoptimized + debuginfo] target(s) in 0.40s
     Running `target/debug/examples/hyper-server`
Error: error:0308010C:digital envelope routines:inner_evp_generic_fetch:unsupported:crypto/evp/evp_fetch.c:375:Global default library context, Algorithm (RC2-40-CBC : 0), Properties ()

Fiddling a bit with it (namely putting some unwrap()s instead of propagating errors), the error gets triggered here:
