grisp/extended_ssl_erlang repository overview

This is a modified Erlang/OTP 25.3.2.2 image that allows customizing the SSL signature function.

Below is an example of how you can provide your custom signing function inside an ssl_dist_optfile⁠:

[
    {server, [
        {key, #{
            algorithm => rsa,
            sign_fun => {my_signing_module, my_signing_fun}
        }}
    ]}
].

You can take a look at the change itself that's built into this image here⁠.
