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 moles 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.
㈡ 怎么使用python crypto
环境：windows8 64位
解决步骤：1.安装pip，Python的官网上去下载，下
1.1选择：下图文件下载到本地磁盘1
1.2 进入cmd输入：python ，将下载的文件解压后里面有setup.py ，拖入cmd窗口，再输入install
1.3 在环境变量的path中加入：C:\Python27\Scripts;
1.4重新打开cmd 窗口中输入pip，回车无报错证明安装成功
2.安装 Microsoft Visual C++ 9.0
由于直接安装安装Crypto模块 会报错如下：因此需要先安装Microsoft Visual C++ 9.0
