Castle protects your users from account compromise

Project description

Build Status

Castle analyzes device, location, and interaction patterns in your web and mobile apps and lets you stop account takeover attacks in real-time.

Installation

pip install castle

Configuration

import and configure the library with your Castle API secret.

from castle.configuration import configuration

# Same as setting it through Castle.api_secret
configuration.api_secret = ':YOUR-API-SECRET'

# For authenticate method you can set failover strategies: allow(default), deny, challenge, throw
configuration.failover_strategy = 'deny'

# Castle::RequestError is raised when timing out in milliseconds (default: 500 milliseconds)
configuration.request_timeout = 1000

# Whitelisted and Blacklisted headers are case insensitive and allow to use _ and - as a separator, http prefixes are removed
# Whitelisted headers
configuration.whitelisted = ['X_HEADER']
# or append to default
configuration.whitelisted = configuration.whitelisted + ['http-x-header']

# Blacklisted headers take advantage over whitelisted elements
configuration.blacklisted = ['HTTP-X-header']
# or append to default
configuration.blacklisted = configuration.blacklisted + ['X_HEADER']

Tracking

Here is a simple example of track event.

from castle.client import Client
from castle import events

castle = Client.from_request(request)
castle.track({
  'event': events.LOGIN_SUCCEEDED,
  'user_id': 'user_id'
})

The client will automatically configure the context for each request.

Signature

from secure_mode import signature

signature(user_id)

will create a signed user_id.

Async tracking

By default Castle sends requests synchronously. To send requests in a background worker you can generate data for a worker:

from castle.client import Client
from castle import events

context = Client.to_context(request)
options = Client.to_options({
  'event': events.LOGIN_SUCCEEDED,
  'user_id': user.id,
  'properties': {
    'key': 'value'
  },
  'user_traits': {
    'key': 'value'
  }
})

and use it later in a way

from castle.client import Client

client = Client(context)
client.track(options)

Exceptions

CastleError will be thrown if the Castle API returns a 400 or a 500 level HTTP response. You can also choose to catch a more finegrained error.
