### Policy Variables

You can use policy variables in the *Resource* element and in string comparisons in the *Condition* element.

    private static final String AES = "AES";

    /**
     * The algorithm to use for the cipher.
     * Default is Blowfish for backward compatibility.
     */
    protected String algorithm = BLOWFISH;

    /**
     * The transformation to use for the cipher when using Key objects.
     * Default is Blowfish to match the algorithm default.
     * <p>

  /**
   * Returns the contained instance if it is present; {@code defaultValue} otherwise. If no default
   * value should be required because the instance is known to be present, use {@link #get()}
   * instead. For a default value of {@code null}, use {@link #orNull}.
   *
   * <p>Note about generics: The signature {@code public T or(T defaultValue)} is overly

Use base64 only if you definitely need to include binary data in JSON, and you can't use files for that.

## Pydantic `bytes` { #pydantic-bytes }

You can declare a Pydantic model with `bytes` fields, and then use `val_json_bytes` in the model config to tell it to use base64 to *validate* input JSON data, as part of that validation it will decode the base64 string into bytes.

# Templates { #templates }

You can use any template engine you want with **FastAPI**.

A common choice is Jinja2, the same one used by Flask and other tools.

There are utilities to configure it easily that you can use directly in your **FastAPI** application (provided by Starlette).

## Install dependencies { #install-dependencies }

Make sure you create a [virtual environment](../virtual-environments.md), activate it, and install `jinja2`:
