How could I encrypt a file_path with ruby-gpgme?

I used the following module

https://github.com/ueno/ruby-gpgme

and my encryption code base is something like this:

  def encrypt_sign(
    plaintext,
    recipient_pubkey,
    sender_privkey,
    binary: nil,
    password: nil
  )
    in_a_directory(binary) do
      options = pinentry_mode(password)

      GPGME::Ctx.new(options) do |ctx|
        import(sender_privkey)  
        import(recipient_pubkey)

        ctx.add_signer(*(find(sender_privkey, :secret)))
        ctx.encrypt_sign(
          find(recipient_pubkey, :public),
          data(plaintext),
          data,
          GPGME::ENCRYPT_ALWAYS_TRUST
        ).to_s
      end
    end
  end

I have no idea how to input file path instead of plaintext file.

any advice is appreciated.

"Plaintext" in the context of cryptography doesn't refer to actual text but rather to the regular data you want encrypted. So all it should take is passing the file contents as plaintext

encrypt_sign(File.read(file_path), recipient_pubkey, ...)
