py-bcrypt

library0.4pypypi✓ verified 86d ago

A minimal bcrypt password hashing and key derivation library for Python. Current version 0.4 is outdated and no longer maintained; most users should switch to bcrypt or passlib.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

bcrypt

✓ import bcrypt

✗ from pybcrypt import bcrypt

The correct import is just 'import bcrypt' after installing py-bcrypt. Common mistake is using a different module name.

Hash a password and verify it.

import bcrypt password = b"my_password" hashed = bcrypt.hashpw(password, bcrypt.gensalt()) if bcrypt.checkpw(password, hashed): print("Password matches")

Debug

Known issues

deprecatedpy-bcrypt is abandoned and not compatible with modern Python (3.x+). Use bcrypt or passlib instead.

fix

Replace py-bcrypt with 'bcrypt' (pip install bcrypt) and update imports accordingly.

affects: all

gotchapy-bcrypt is extremely slow compared to modern alternatives (e.g., bcrypt, argon2). It uses a pure Python implementation.

fix

Switch to a C-extension based library like bcrypt.

affects: all

gotchaThe salt generation with gensalt() returns bytes; ensure you pass bytes to hashpw.

fix

Always use bytes: bcrypt.hashpw(password.encode(), bcrypt.gensalt()).

affects: all

Errors

Common errors & fixes

ModuleNotFoundError: No module named 'bcrypt'

The library is not installed or import name is wrong.

fix

Install with 'pip install py-bcrypt' and import as 'import bcrypt'.

TypeError: Unicode-objects must be encoded before hashing

Passing a string instead of bytes to bcrypt functions.

fix

Encode the string: bcrypt.hashpw(password.encode('utf-8'), bcrypt.gensalt()).
