Generating keys securely with the secrets and hashlib modules

In this section, we are going to review the main modules Python provides for generating keys and passwords in a secure way.

Generating keys securely with the secrets module

The secrets module is used to generate cryptographically strong random numbers, suitable for managing data such as passwords, user authentication, security tokens, and related secrets.

In general, the use of random numbers is common in various scientific computing applications and cryptographic applications. With the help of the secrets module, we can generate reliable random data that can be used by cryptographic operations.

The secrets module derives its implementation from the os.urandom() and SystemRandom() methods, which interact with the operating system to ensure cryptographic randomness and can help you accomplish the following tasks:
