pycryptodome 3.4.7

Cryptographic library for Python

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:

pip install pycryptodome

All modules are installed under the Crypto package.

Check the pycryptodomex project for the equivalent library that works under the Cryptodome 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-256 curve only)
  • 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
  • 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.

All the code can be downloaded from GitHub.
