FastStream Redis Security#

This chapter discusses the security options available in FastStream and how to use them.

Security Objects#

FastStream allows you to enhance the security of applications by using security objects when creating brokers. These security objects encapsulate security-related configurations and mechanisms. Security objects supported in FastStream for Redis are:

1. BaseSecurity Object#

Purpose: The BaseSecurity object wraps ssl.SSLContext object and is used to enable SSL/TLS encryption for secure communication between FastStream services and external components such as message brokers.

Usage:

1

3
4
5
6
7
8
9

import ssl

from faststream.redis import RedisBroker
from faststream.security import BaseSecurity

ssl_context = ssl.create_default_context()
security = BaseSecurity(ssl_context=ssl_context)

broker = RedisBroker(security=security)

2. SASLPlaintext Object with SSL/TLS#

Purpose: The SASLPlaintext object is used for authentication in SASL (Simple Authentication and Security Layer) plaintext mode. It allows you to provide a username and password for authentication.

Usage:

import ssl

from faststream.redis import RedisBroker
from faststream.security import SASLPlaintext

ssl_context = ssl.create_default_context()
security = SASLPlaintext(
    ssl_context=ssl_context,
    username="admin",
    password="password", 
)

broker = RedisBroker(security=security)
