PyCryptodome
|
||
|
|
============
|
||
|
|
|
||
|
|
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.
