actix-web-lets-encrypt

This software makes it fairly easy to use Lets Encrypt with Actix web.

Proof-of-concept

The code in this repository has been lightly tested, but I am unhappy with the API I've constructed. I especially dislike the split between the app_encryption_enabler and the server_encryption_enabler. I'm new to Rust and wanted to write something and then ask for suggestions for a better API.

I haven't yet written documentation for the public functions because I think it's likely they'll change. However, if the example below isn't sufficient to illustrate the sort of behavior I'm trying to make available I can go ahead and document what is present.

This version only works with openssl.

// Although the following code doesn't run as-is, it's basically a
// simplified version of code that has run.  Unfortunately, there's no
// way to provide a sample that will run 100% out of the box, because
// to use a certificate you must have DNS pointing a domain to the host
// you're running this on.
