Dependency errors

[nshafer]

I am getting the following warnings after installing EasySSL 1.3, and doing a deps.get or deps.compile

==> easy_ssl
Compiling 1 file (.ex)
warning: :crypto.hash/2 defined in application :crypto is used by the current application but the current application does not depend on :crypto. To fix this, you must do one of:

  1. If :crypto is part of Erlang/Elixir, you must include it under :extra_applications inside "def application" in your mix.exs

  2. If :crypto is a dependency, make sure it is listed under "def deps" in your mix.exs

  3. In case you don't want to add a requirement to :crypto, you may optionally skip this warning by adding [xref: [exclude: [:crypto]]] to your "def project" in mix.exs

  lib/easy_ssl.ex:201: EasySSL.fingerprint_cert/1

warning: :public_key.pkix_decode_cert/2 defined in application :public_key is used by the current application but the current application does not depend on :public_key. To fix this, you must do one of:

  1. If :public_key is part of Erlang/Elixir, you must include it under :extra_applications inside "def application" in your mix.exs

  2. If :public_key is a dependency, make sure it is listed under "def deps" in your mix.exs

  3. In case you don't want to add a requirement to :public_key, you may optionally skip this warning by adding [xref: [exclude: [:public_key]]] to your "def project" in mix.exs

  lib/easy_ssl.ex:76: EasySSL.parse_der/2

warning: :public_key.pkix_sign_types/1 defined in application :public_key is used by the current application but the current application does not depend on :public_key. To fix this, you must do one of:

  1. If :public_key is part of Erlang/Elixir, you must include it under :extra_applications inside "def application" in your mix.exs

  2. If :public_key is a dependency, make sure it is listed under "def deps" in your mix.exs

  3. In case you don't want to add a requirement to :public_key, you may optionally skip this warning by adding [xref: [exclude: [:public_key]]] to your "def project" in mix.exs

  lib/easy_ssl.ex:273: EasySSL.parse_signature_algo/1

Generated easy_ssl app

This is with:

elixir          1.12.3-otp-24
erlang          24.1

If I put xref: [exclude: [:crypto, :public_key]] in the mix.exs project() function, the warnings go away. I have no idea if this module actually needs those applications to be running.. my guess is not. If that's the case, I can create a PR with this fix.

Thanks,
