PyCryptodome是PyCrypto的一个分支。基于PyCrypto2.6.1，多了以下特性：
- Authenticated encryption modes (GCM, CCM, EAX, SIV)
- Accelerated AES on Intel platforms via AES-NI
- First class support for PyPy
- SHA-3 hash algorithm
- Salsa20 stream cipher
- 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

0x01 安装
0x02 使用
跟PyCrypto2.6用法类似，以下以AES为例：
from Crypto.Cipher import AES
key=‘1234567890abcdef‘
obj=AES.new(key,AES.MODE_ECB)
cipher=obj.encrypt(‘message: pcat.cc‘)
