PKCS#1 support

[apawlucz-cisco]

Hello!

When I try to start the embedded server using PKCS#1 formatted PEM certificates like this:

server = Server(
    app,
    address="0.0.0.0",
    port=8000,
    interface=Interfaces.ASGI,
    ssl_cert=self.cert_file_path(),
    ssl_key=self.key_file_path(),
    ssl_key_password=<password>,
)

The server crashes with:

thread '<unnamed>' (127691) panicked at src/tls.rs:76:22:

I tried the same, but using PKCS#8 format - it works fine.

Is it deliberate decision not to support PKCS#1 format? I do understand PKCS#1 is somewhat legacy, though I did not found any information whether granian does or does not support PKCS#1 by design.

Thank you!

Yeah, PKCS#1 is not supported.
The reason is not stated anywhere is simply because I never encountered a PEM private-key encoded with something other than PKCS#8. But I guess we can add a line in the readme.
