PyCryptodome is a self-contained Python package of low-level cryptographic primitives.

It supports Python 2.4 or newer, all Python 3 versions and PyPy.

You can install it with a simple:

pip install pycryptodome

PyCryptodome is a fork of PyCrypto. It brings the following enhancements with respect to the last official version of PyCrypto (2.6.1):

• Authenticated encryption modes (GCM, CCM, EAX, SIV, OCB)
• Accelerated AES on Intel platforms via AES-NI
• First class support for PyPy
• SHA-3 (including SHAKE XOFs) and BLAKE2 hash algorithms
• Salsa20 and ChaCha20 stream ciphers
• scrypt and HKDF
• Deterministic DSA
• Password-protected PKCS#8 key containers
• Shamir's Secret Sharing scheme
• Random numbers get sourced directly from the OS (and not from a CSPRNG in userspace)
• Simplified install process, including better support for Windows
• Cleaner RSA and DSA key generation (largely based on FIPS 186-4)
• Major clean ups and simplification of the code base
