no releases from root/pypi are included.
PyCryptodome is a self-contained Python package of low-level cryptographic primitives.
It supports Python 2.7, Python 3.5 and newer, and PyPy.
You can install it with:
pip install pycryptodomex
All modules are installed under the Cryptodome package.
Check the pycryptodome project for the equivalent library that works under the Crypto package.
PyCryptodome is a fork of PyCrypto. It brings several enhancements with respect to the last official version of PyCrypto (2.6.1), for instance:
- Authenticated encryption modes (GCM, CCM, EAX, SIV, OCB)
- Accelerated AES on Intel platforms via AES-NI
- First class support for PyPy
- Elliptic curves cryptography (NIST P-curves; Ed25519, Ed448)
- Better and more compact API (nonce and iv attributes for ciphers, automatic generation of random nonces and IVs, simplified CTR cipher mode, and more)
- SHA-3 (including SHAKE XOFs) and BLAKE2 hash algorithms
- Salsa20 and ChaCha20 stream ciphers
- scrypt and HKDF
- Deterministic (EC)DSA and EdDSA
- 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
PyCryptodome is not a wrapper to a separate C library like OpenSSL. To the largest possible extent, algorithms are implemented in pure Python. Only the pieces that are extremely critical to performance (e.g. block ciphers) are implemented as C extensions.
