## Multiple models

Here's a general idea of how the models could look like with their password fields and the places where they are used:

as the support for external CAs is more mature than external discovery servers. This supports some additional
configuration, a `CredentialFetcher` which allows fetching a token from places other than a file (for example, a local
metadata server), and a `TokenExchanger` which allows exchanging a token for another form to match the CA server requirements.

   * it is returned directly. Otherwise, a new array of size {@code minLength + padding} is
   * returned, containing the values of {@code array}, and zeroes in the remaining places.
   *
   * @param array the source array
   * @param minLength the minimum length the returned array must guarantee
   * @param padding an extra amount to "grow" the array by if growth is necessary

The **default** value of the **function parameter** is the **actual default** value, that's more intuitive with Python in general. 😌

The content of each of these strings can have any format, but should not contain spaces.

These scopes represent "permissions".

In OpenAPI (e.g. the API docs), you can define "security schemes".

When one of these security schemes uses OAuth2, you can also declare and use scopes.

Each "scope" is just a string (without spaces).

	// Decode signature string to binary byte-sequence representation is required
	// as Base64 encoding of a value is not unique:
	// For example "aGVsbG8=" and "aGVsbG8=\r" will result in the same byte slice.
	signature1, err := base64.StdEncoding.DecodeString(sig1)
	if err != nil {
		return false
	}
	signature2, err := base64.StdEncoding.DecodeString(sig2)
	if err != nil {
		return false
	}
