bcrypt

Warnings

• breaking Passing a password longer than 72 bytes to hashpw now raises a ValueError; previously, it was silently truncated.
  Fix: Ensure passwords are 72 bytes or shorter before hashing.
• deprecated Support for Python 3.7 has been dropped in version 4.3.0.
  Fix: Upgrade to Python 3.8 or later.
• gotcha bcrypt requires a C compiler and a Rust compiler (minimum supported Rust version is 1.56.0) for building from source.
  Fix: Install the necessary compilers or use pre-built wheels.

Install

• pip install bcrypt Install bcrypt

Imports

  Ensure 'bcrypt' is imported directly; avoid 'from bcrypt import *' to prevent namespace pollution.

Quickstart

A simple example demonstrating how to hash and check passwords using bcrypt.

import bcrypt

# Hash a password
password = b"supersecret"
salt = bcrypt.gensalt()
hash = bcrypt.hashpw(password, salt)

# Check a password
if bcrypt.checkpw(password, hash):
    print("Password matches")
else:
    print("Password does not match")
