How to generate encrypt signature in Elixir

Description
Elixir script to generate encrypt signature based on other languages scripts found here. Hope it’s useful for someone :slight_smile:

defmodule MyZoomApp.GenerateSignature do
  def perform(api_key, api_secret, meeting_number, role) do
    ts =
      UTCDateTime.utc_now()
      |> UTCDateTime.to_epoch(:unix, :millisecond)
             |> Kernel.-(30000)

    msg = :base64.encode("#{api_key}#{meeting_number}#{ts}#{role}")

    hmac =
      :sha256
       |> :crypto.hmac(api_secret, msg)
               |> :base64.encode

    :base64.encode("#{api_key}.#{meeting_number}.#{ts}.#{role}.#{hmac}")
  end
end
