PyCryptodome安装使用方法

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

pip install PyCryptodome

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')
