PyNaCl is a Python binding to libsodium, a fork of the Networking and Cryptography (NaCl) library. It provides high-level access to modern cryptographic primitives including encryption, signatures, hashing, and password hashing.
Use cases
- encrypt and decrypt messages with secret-key or public-key cryptography in python
- sign and verify data with digital signatures
- hash passwords securely in python
- derive encryption keys from passwords
- compute message authentication codes (MACs)
When to choose
- you need well-audited, easy-to-use cryptographic primitives in Python
- you want libsodium's high-level crypto API from Python
- you need authenticated encryption or Ed25519 signatures
When to avoid
- you need low-level control over cipher primitives or custom protocols
- you need TLS/SSL or X.509 certificate handling
- you are working outside Python
