"""RSA Keys.

The RSA key saved into our codebase contains an id (unique), the public and
private RSA key. Those keys are used to encrypt in the frontend the username
and user's password. The id is also passed along in the request.

Getting back the id allows us to fetch the private rsa key, which is used to
decrypt the request.
