Here's a good function header given the following:
I wrote the below code

    def b64_encode_meta(crypto_meta):
        return {name: (base64.b64encode(value).decode() if (name in ('iv', 'key')) else (b64_encode_meta(value) if isinstance(value, dict) else value)) for (name, value) in crypto_meta.items()}
    return urlparse.quote_plus(json.dumps(b64_encode_meta(crypto_meta), sort_keys=True))

What's a good function header?
