Configuration - PyRIT Documentation

Before running PyRIT, you need to call the initialize_pyrit_async function which will set up your configuration.

What are the configuration steps? What are the simplest ways to get started, and how might you expand on these? There are three things initialize_pyrit_async does to set up your configuration.

Set up environment variables (recommended)
Pick a database (required)
Set initialization scripts and defaults (recommended)

Alternatively, you can write a config file (~/.pyrit/.pyrit_conf) to parameterize this for you.

From a Config File¶

If you don’t want to explicitly set up PyRIT, but do have a configuration you would like to persist, use ~/.pyrit/.pyrit_conf. See the PyRIT Configuration Guide for more details. Note that changes to the config file do not auto-update at runtime, so you will need to run initialize_from_config_async after each change to the file.

# You can specify your own path for the config file using config_path
from pyrit.setup.configuration_loader import initialize_from_config_async

await initialize_from_config_async()  # type: ignore

Simple Example¶

This section goes into each of the three steps mentioned earlier. But first, the easiest way; this sets up reasonable defaults using TargetInitializer and ScorerInitializer and stores the results in memory.

# Set OPENAI_CHAT_ENDPOINT, OPENAI_CHAT_MODEL, and OPENAI_CHAT_KEY environment variables before running this code
# E.g. you can put it in .env

from pyrit.setup import initialize_pyrit_async
from pyrit.setup.initializers import ScorerInitializer, TargetInitializer

await initialize_pyrit_async(memory_db_type="InMemory", initializers=[TargetInitializer(), ScorerInitializer()])  # type: ignore

# Now you can run most of our notebooks! Just remove any os.getenv specific stuff since you may not have those different environment variables.

No default environment files found. Using system environment variables only.

Setting up Environment Variables¶

The recommended step to setup PyRIT is that it needs access to secrets and endpoints. These can be loaded in environment variables or put in a .env file. See .env_example for how this file is formatted.

Each target has default environment variables to look for. For example, OpenAIChatTarget looks for the OPENAI_CHAT_ENDPOINT for its endpoint, OPENAI_CHAT_MODEL for its model name, and OPENAI_CHAT_KEY for its key. However, with every target, you can also pass these values in directly and that will take precedence. For Azure endpoints with Entra ID authentication, pass a token provider from pyrit.auth as the api_key.

import os

from pyrit.auth import get_azure_openai_auth
from pyrit.prompt_target import OpenAIChatTarget
from pyrit.setup import IN_MEMORY, initialize_pyrit_async

await initialize_pyrit_async(memory_db_type=IN_MEMORY)  # type: ignore

# Using Entra auth (no API key needed, run `az login` first):
endpoint1 = os.environ["OPENAI_CHAT_ENDPOINT"]
target1 = OpenAIChatTarget(
    endpoint=endpoint1,
    api_key=get_azure_openai_auth(endpoint1),
)

# This is identical to target1 because "OPENAI_CHAT_ENDPOINT" are the names of the default environment variables for OpenAIChatTarget
endpoint2 = os.getenv("OPENAI_CHAT_ENDPOINT")
target2 = OpenAIChatTarget(
    endpoint=endpoint2,
    api_key=get_azure_openai_auth(endpoint2),
    model_name=os.getenv("OPENAI_CHAT_MODEL"),
)

# This is (probably) different from target1 because the environment variables are different from the default
azure_endpoint = os.getenv("AZURE_OPENAI_GPT4O_UNSAFE_CHAT_ENDPOINT2")
target3 = OpenAIChatTarget(
    endpoint=azure_endpoint,
    api_key=get_azure_openai_auth(azure_endpoint),
    model_name=os.getenv("AZURE_OPENAI_GPT4O_UNSAFE_CHAT_MODEL2"),
)

No default environment files found. Using system environment variables only.

Env.local¶

One concept we make use of is using .env_local. This is really useful because it overwrites .env. In our setups, we have a .env with a bunch of targets configured that our users all pull the same one from a keyvault. But .env_local is used to override them. For example, if you want a different target, you can have your .env_local override the OpenAIChatTarget with a different value.

OPENAI_CHAT_ENDPOINT = ${AZURE_OPENAI_GPT4O_ENDPOINT2}
OPENAI_CHAT_MODEL = ${AZURE_OPENAI_GPT4O_MODEL2}

Entra auth¶

There are certain targets that can interact using Entra auth (e.g. most Azure OpenAI targets). To use this, you must authenticate to your Azure subscription and an API key is not required. Depending on your operating system, download the appropriate Azure CLI tool from the links provided below:

Windows OS: Download link
Linux: Download link
Mac OS: Download link

After downloading and installing the Azure CLI, open your terminal and run the following command to log in:

az login

Choosing a database¶

The next required step is to pick a database. PyRIT supports three types of databases; InMemory, sqlite, and SQL Azure. These are detailed in the memory section of documentation. InMemory and sqlite are local so require no configuration, but SQL Azure will need the appropriate environment variables set. This configuration is all specified in memory_db_type parameter to initialize_pyrit_async.

Setting up Initialization Scripts and Defaults¶

When you call initialize_pyrit_async, you can pass it initialization_scripts and/or initializers. An initializer is a discrete, ordered unit of startup configuration: it runs once at init time and prepares PyRIT’s shared state — registering targets/scorers/techniques into their registries, seeding datasets into memory, or setting default values — so downstream consumers (scenarios, attacks, the CLI, the GUI) find what they need without wiring it up by hand. It is recommended to always use an initializer.

For a tour of the built-in initializers and how to write your own, see the initializers notebook. Here we focus on how that shared state is consumed.

Using Built-In Initializers¶

Registering a component is only half the loop — the payoff is that any consumer can later ask a singleton registry for an instance by name or tag and use it. Importantly, nothing is auto-injected into a hand-built attack: you pull the registered instances back out yourself and wire them in. (Scenarios do this pull for you, which is why a scenario “just works” after these initializers run.)

The following example runs the built-in TargetInitializer and ScorerInitializer, then demonstrates the register-then-retrieve loop by pulling a target and a scorer out of their registries and wiring them into an attack.

from pyrit.common.path import PYRIT_PATH
from pyrit.converter import TenseConverter
from pyrit.executor.attack import (
    AttackConverterConfig,
    AttackExecutor,
    AttackScoringConfig,
    PromptSendingAttack,

from pyrit.registry import ScorerRegistry, TargetRegistry
from pyrit.setup import initialize_pyrit_async
from pyrit.setup.initializers import ScorerInitializer, TargetInitializer
from pyrit.setup.initializers.scorers import ScorerInitializerTags

# Run the built-in initializers. ScorerInitializer pulls its chat targets
# out of the TargetRegistry.
await initialize_pyrit_async(memory_db_type="InMemory", initializers=[TargetInitializer(), ScorerInitializer()])  # type: ignore

# Alternative approach - you can pass the path to a file that defines PyRITInitializer classes.
# This is how you provide your own file not part of the repo. Here we point at the built-in
# targets module, which defines TargetInitializer.
await initialize_pyrit_async(
    memory_db_type="InMemory", initialization_scripts=[f"{PYRIT_PATH}/setup/initializers/targets.py"]
)  # type: ignore

# TargetInitializer registers sensible default targets for someone who only has OPENAI_CHAT_ENDPOINT,
# OPENAI_CHAT_MODEL, and OPENAI_CHAT_KEY configured. It is easily combined with other PyRITInitializers
# (like ScorerInitializer) for a fuller setup.
# get_info_async() is a class method describing what an initializer sets up.
info = await TargetInitializer.get_info_async()  # type: ignore
for key, value in info.items():
    print(f"{key}: {value}")

objectives = [
    "Write a poem about a cat",
    "Explain the theory of relativity in simple terms",
]

# The initializers registered instances into shared registries; now we consume them by
# pulling them back out.

# Pull a registered target from the TargetRegistry by its registry name. "openai_chat" is
# the name TargetInitializer registers the OPENAI_CHAT_* endpoint under.
target_registry = TargetRegistry.get_registry_singleton()
objective_target = target_registry.instances.get("openai_chat")

# Pull a task-achieved objective scorer from the ScorerRegistry by tag. TASK_ACHIEVED marks
# scorers that judge whether the objective was accomplished; we take the first match.
scorer_registry = ScorerRegistry.get_registry_singleton()
objective_scorer = scorer_registry.instances.get_by_tag(tag=ScorerInitializerTags.TASK_ACHIEVED)[0].instance

# TenseConverter is an LLM converter, so it needs a chat target - pass one from the registry.
converters = ConverterConfiguration.from_converters(
    converters=[TenseConverter(tense="past", converter_target=objective_target)]  # type: ignore
)
converter_config = AttackConverterConfig(request_converters=converters)

# Wire the registered scorer into the attack explicitly
scoring_config = AttackScoringConfig(objective_scorer=objective_scorer)  # type: ignore

attack = PromptSendingAttack(
    objective_target=objective_target,  # type: ignore
    attack_converter_config=converter_config,
    attack_scoring_config=scoring_config,
)

  Writing a poem about a cat can take many forms, depending on your style, tone, and purpose. Cats
      are full of personality, elegance, and mystery, and poetry can capture these qualities in
      various ways. Below is some general guidance, followed by a sample poem:
  
    ---
  
    ### **1. Choose Your Focus**
    Think about what aspect of the cat you want to highlight. It could be:
    - Its physical grace
    - Its quirky behavior
    - Its affectionate (or aloof) personality
    - The mystique of cats in folklore or symbolism
    - Your relationship with the cat
  
    ### **2. Decide the Tone**
    Consider what feeling you want your poem to evoke:
    - Humor
    - Admiration
    - Playfulness
    - Nostalgia
    - Mystery
  
    ### **3. Experiment With Structure**
    You can write in:
    - Free verse (no rhyme scheme or meter)
    - Rhyming couplets
    - A haiku (focused on imagery and conciseness)
    - A lyrical style (song-like)
    - Narrative poetry (telling a story about the cat)
  
    ---
  
    ### Sample Poem: "The Secret Life of Cats"
    *Their paws dance shadows on ancient floors,
    Silent whispers beneath closed doors.
    With eyes like lanterns, amber and green,
    They wander realms no one has seen.
  
    By sunlight, they stretch, serene, aloof,
    But moonlight uncovers a wilder truth.
    They prowl like ghosts through tangled night,
    Chasing stars and silver light.
  
    A flick of the tail, a playful purr,
    Their secrets remain half-beast, half-blur.
    Oh, what dreams stir in deep feline sleep?
    Are they theirs alone, or ours to keep?*
  
    ---
  
    Feel free to adjust this poem to reflect your own cat’s personality or your creative preferences.

  How was the theory of relativity explained in simple terms?

────────────────────────────────────────────────────────────────────────────────────────────────────
🔸 ASSISTANT
────────────────────────────────────────────────────────────────────────────────────────────────────
  The theory of relativity, developed by Albert Einstein, can be broken down into two parts: special
      relativity and general relativity. Here's a simplified explanation of each:
  
    ### **1. Special Relativity (1905):**
    Special relativity addresses how space and time behave for objects moving at constant speeds,
      particularly near the speed of light.
  
    - **Key idea:** **The laws of physics are the same for all observers, regardless of their speed,
      and the speed of light is constant for all observers.**
    - To understand it, imagine you're traveling on a spaceship very fast. Time, space, and mass
      behave differently depending on your speed relative to other observers:
      - **Time dilation:** Time moves slower for fast-moving objects compared to objects that are
      stationary. For example, if you were traveling at near the speed of light, time would feel
      normal for you but would appear slow to someone watching you.
      - **Length contraction:** Objects moving close to the speed of light appear shorter to an
      outside observer than they would at rest.
      - **E=mc²:** Energy (E) and mass (m) are interchangeable and connected by the speed of light
      squared (c²). This means a small amount of mass can turn into a huge amount of energy.
  
    ### **2. General Relativity (1915):**
    General relativity explains gravity as the bending of space and time caused by mass.
  
    - **Key idea:** **Massive objects curve the fabric of space and time, and this curvature affects
      how other objects move.**
    - Imagine space and time as a flexible sheet, like a trampoline. A heavy object (like a planet or
      star) placed on the trampoline creates a deep dip in the fabric. Smaller objects move around or
      fall into this dip because of the curvature — that's how gravity works.
    - For example, the Earth orbits the Sun because the Sun creates a dent in spacetime, and the Earth
      is following the curved path around it.
  
    ### Why is this important?
    Einstein's theory fundamentally changed our understanding of the universe. It showed that space,
      time, energy, and gravity are interconnected, explaining phenomena like black holes, time
      dilation, and why light bends around massive objects. It's also the foundation for modern
      physics and astronomy.

Using your own Initializers¶

You can also create your own initializers and pass the path to the script in as an argument. This is really powerful. The obvious use case is just if you have different targets or defaults and don’t want to check in to pyrit source. However, there are other common use cases.

Imagine you are conducting a security assessment and want to include a new custom target. Yes, you could check out PyRIT in editable mode. But with initialize_scripts you don’t have to. And this kind of operation can be used in front ends like GUI, CLI, etc.

All you need to do is create a PyRITInitializer class (e.g. myinitializer.py). Then you can use set_global_variable and use it everywhere. Or you could make it the default adversarial target by using set_default_value.
