pyca/bcrypt is a Python library providing bcrypt password hashing and a bcrypt_pbkdf key derivation function. It offers salted hashing with an adjustable work factor for securely storing and verifying user passwords.
Use cases
- hash user passwords in a python web app
- verify passwords against bcrypt hashes
- generate salted password hashes with adjustable cost
- derive encryption keys from passwords with bcrypt_pbkdf
- migrate legacy password storage to bcrypt
When to choose
- you need battle-tested bcrypt hashing in Python
- you want a simple hashpw/checkpw API
- you need OpenSSH-compatible bcrypt_pbkdf key derivation
When to avoid
- you can use argon2id or scrypt instead, as the maintainers recommend
- you need general-purpose encryption rather than password hashing
- your environment cannot build Rust/C extensions
