-# The `cipher_suite` is set to `:strong` to support only the
-# latest and more secure SSL ciphers. This means old browsers
-# and clients may not be supported. You can set it to
-# `:compatible` for wider support.
-#
-# `:keyfile` and `:certfile` expect an absolute path to the key
-# and cert in disk or a relative path inside priv, for example
-# "priv/ssl/server.key". For all supported SSL configuration
-# options, see https://hexdocs.pm/plug/Plug.SSL.html#configure/1
-#
-# We also recommend setting `force_ssl` in your endpoint, ensuring
-# no data is ever sent via http, always redirecting to https:
-#
-#     config :wabanex, WabanexWeb.Endpoint,

-# and configuration from environment variables.
