Installation

Supported Platforms

Passlib requires Python 3.9 or newer.

Passlib should work with all operating systems and environments, as it contains builtin fallbacks for almost all OS-dependent features.

Warning

Passlib 1.8 drops support for Python < 3.9, Jython and PyPy. Starting with 1.10, versions that have reached EOL will no longer be supported.

Optional Libraries

• bcrypt If installed, this will be used to handle passlib.hash.bcrypt and passlib.hash.bcrypt_sha256 hashes.
  Use pip install passlib[bcrypt] to get the recommended bcrypt setup.

• argon2_cffi If argon2_cffi is installed, it will be used to provide support for the passlib.hash.argon2 hash algorithm.
  Use pip install passlib[argon2] to get the recommended argon2 setup.

• cryptography If installed, will be used to enable encryption of TOTP secrets for storage (see passlib.totp).
  Use pip install passlib[totp] to get the recommended TOTP setup.

Installation Instructions

To install from PyPI using pip:

pip install passlib

As noted above, you can ensure you have feature-specific extras installed via any of:

pip install passlib[argon2]
pip install passlib[bcrypt]
pip install passlib[totp]
